15 Common Betta Fish Diseases (With Photos): Prevention and Treatment
Betta fish suffers from a number of health conditions, but the good news to the keepers of this type of fish is that these health problems can be prevented and also treated. If the infections occur in the aquarium, they can be easily identified and treated effectively.
This article covers all the common diseases and illnesses of betta fish, their prevention, diagnosis and treatment. So if you keep the Siamese fighting fish at home, read on to learn how you can keep your aquatic pet healthy.
Betta fish diseases and illnesses are categorized into fungal, parasitic and bacterial. Most fungal infections result from previous health conditions. Parasitic ailments are the most contagious and can be introduced into the aquarium by new fish. The most common causes of bacterial sicknesses include poor quality water and inappropriate fish handling methods.
The Common Diseases of Betta Fish, in Brief
- Fin and Tail Rot
- Columnaris
- Hemorrhagic
- Dropsy
- Pop Eye
- Eyecloud
- Mouth Fungus
- Furunculosis
- Fish Fungus
- Velvet
- Ich
- Anchor Worms
- Hole in the Head
- Swim Bladder Disorder
- Betta Tumors
1. Fin and Tail Rot
As the name suggests, this disease affects the fins and tail of betta. It can be caused by bacteria or fungi. The fins and tail appear to melt away as a result of rotting.
It can be prevented by keeping the aquarium or living conditions of the fish clean.
Fin and Tail Rot can be treated by medications containing antibiotics, such as trimethoprim, erythromycin and sulfadimidine.
If it is effectively treated, the fatality is medium.
If you have had Fin and Tail Rot affecting your fish, you may have tried medications such as Tetracycline, Jungle Fungus Eliminator (JFE), Maracyn or Melafix. But the truth of the matter is that these medications are not quite effective in treating this infection, and some even kill your fish.
I have had little success with JFE and the other medications showed no success - they even worsened the condition. According to my own experience, the most effective medication for Fin and Tail Rot is 
The medication is itself a 5-day treatment, and it comes with clear instructions on how to use it. The most amazing thing about this treatment is that it starts to give positive results from day one! According to the manufacturer, it can also deal with pop eye, body rot, raised veins, ulcers, 'redness', cloudy eyes and other health conditions.
If you have the Fin and Tail Rot disease or the related infections in your aquarium, I would encourage you to go for this medication. I have been using it since I discovered it in 2010 and I have had no disappointments with it.
2. Columnaris
This is a bacterial disease that causes the fins to rag and fray. It also causes skin ulcers or lesions, white spots on the mouth, cottony growth on the mouth, scales and fins, and gills discoloration. The fish can have breathing difficulties as a result of the gill infection.
The sickness can be prevented by treating open wounds and fungal infections. It can also be prevented by avoiding factors, such as limited oxygen, water hardness and overcrowding in the aquarium.
Columnaris can be treated by Oxytetracycline and antibiotics containing Sulfa 4 TMP, TMP Sulfa and triple sulfa.
If the infected fish is not treated, it can die in less than 72 hours.
3. Hemorrhagic
Commonly known as Redmouth, Hemorrhagic causes serious bleeding inside the mouth and eyes of the fish.
The disease can be prevented by disinfecting the aquarium to kill Yersinia Ruckeri, which is the bacteria causing the illness.
The treatment of Hemorrhagic is possible with antibiotics such as ampicillin.
The infection is treatable, which means that the fatality is low.
4. Dropsy
This is a deadly ailment that affects the kidneys. The infected fish can have swollen abdomen as a result of accumulation of internal fluid.
Some more symptoms include; outward-sticking scales and sunken eyes.
The bacterial infection can be prevented by keeping the aquarium clean. It can also be prevented by feeding fish with vitamins-rich foods.
There is no known cure for Dropsy but medications, such as Betta Revive, can help with the condition.
Most fish that suffer from Dropsy do not survive.
5. Pop Eye
This disorder causes swelling on one or both eyes. The swelling can be a tumor or viral infection.
Pop Eye is usually a symptom of a disease and can be avoided by preventing infections in the aquarium.
Antibiotics such as Tetracycline can cure the ailment.
Most fish that suffer from Pop Eye survives at the end.
6. Eyecloud
Commonly known as Cloudy cornea, this disease causes white films on the eyes.
It can be prevented by improving the quality of water. A water conditioner is needed to make the water safer for the aquatic animal.
Eyecloud can be treated by antibiotics such as Metafix and Fungus Clear.
The bacterial sickness is not fatal but can impair vision.
7. Mouth Fungus
This is actually a bacterial disease, and it causes white lines and clumps around the lips and mouth of the fish.
It can be avoided by keeping the water clean.
Amoxicillin as an antibiotic can cure Mouth Fungus.
The infected fish cannot survive if the illness is not treated early enough.
8. Furunculosis
The symptoms of Furunculosis include skin ulcers and open red sores.
Improving water quality can effectively prevent the disease.
Fungus Clear as an antibiotic can treat this bacterial ailment.
Furunculosis can kill fish that doesn’t receive treatment in time.
9. Fish Fungus
This is a fungal disease that originates from previous infections. The affected betta usually has cotton-like growths or slime (mucus) on the skin.
It can be prevented by avoiding primary infections and injuries and keeping the aquarium clean.
Antibiotics such as Methylene Blue and Fungus Clear can cure Fish Fungus. It can also be treated effectively by the Bettafix Remedy mentioned below.
The sickness can become fatal if it is not treated early enough.
10. Velvet
Betta infected with Velvet appears to have a rusty skin.
The parasitic disease can be prevented by improving the quality of water and ensuring the living conditions are stress-free. Water conditioners are some of the best substances to improve the living conditions.
It is highly contagious but it can be treated fully by 
With all these healing components, this remedy can also be used to treat all the other diseases, illnesses, sickness and disorders listed on this article. I have been keeping bettas for almost 15 years, and I have seen this medication heal my aquatic pets. I recommend that you use it to prevent, control and treat many ill-health conditions.
If Velvet is not treated early enough, the infected fish dies in a matter of days.
11. Ich
Also known as White Spot, Ich or Ick is a parasitic disease that causes white dots or spots on the skin of betta fish.
It can be prevented by changing the water regularly.
The sickness can be treated by Fish-zole, Malachite Green or salt baths.
It is very easy to deal with the illness if treatment starts early.
12. Anchor Worms
This is a parasitic disease that attacks the tail or fins. The affected parts appear red and swollen and have protruding worms and threads of slime.
It can be prevented by treating any newly infected fish and keeping the water clean.
Some antibiotics such as Methylene Blue and Parasite Clear can cure the disease.
The ailment can become fatal if it is not treated early enough.
13. Hole in the Head
Betta infected with Hole in the Head have an abrasion on the head that looks like a pinhole.
The parasitic infection can be prevented by cleaning water off carbon.
Parasite Clear is an antibiotic that can cure the disease.
The infected fish usually dies after a few days if it is not treated early enough.
14. Swim Bladder Disorder
Also known as flipover, this disorder forces the fish to float at the surface of the water. The affected fish swims sideways or upside-down and can also lie at the bottom of tank. It is caused by constipation, poor water conditions, parasite or bacterial infections and enlarged organs.
It can be controlled by maintaining a high quality water, avoiding overstocking and feeding the fish with the right amount of fresh and fiber-rich foods.
When it comes to the treatment, the swim bladder disorder can be stopped by raising the water temperature, letting the fish fast for some days and then feeding them with cooked peas.
15. Betta Tumors
Betta tumors are usually cancer lumps or minor bumps/cysts under the skin of the fish. They mainly affect the reproductive organs, gills, tail and abdomen, and are caused by genetic mutations and viral infections.
The tumors can be controlled by feeding the fish with healthy foods, maintaining a clean tank, treating other infections and keeping carcinogenic substances away from the tank.
As far as treatment is concerned, the malignant tumors can be hard to cure, but some simple surgical operations can help. The benign tumors and cysts can be treated in a number of ways depending on the cause the lump or bump.

Conclusion
Now you have it. With this information, you can keep betta without any worries. Some fish can develop behavioral conditions, such as stress, lethargy and poor appetite, but you shouldn’t be worried about these short-lived conditions, especially if your fish is new in the aquarium.
Important: If you haven't found a solution for your fish yet, do not fail to check the comments, questions and answers below!
Have you ever dealt with any of the above Betta fish infections and diseases?
Questions & Answers
My betta has been hanging out at the bottom of the tank, she doesn’t really eat. Sometimes she’ll zip around the tank and then right back to the bottom. I tried betta fix. What else can I do ?
Well, you need to check other signs of sickness in her. If she lacks these signs, then she might not be sick. It is actually normal for fish to stay at the bottom or eat less/not to eat for a certain period.
Helpful 24Why did my beta kill itself by butting its head onto the tank?
Didn't you see him/her butting? He/she could have developed an infection on the head.
Helpful 23My Betta won't move, and his fins are turning white. He has a white fuzzy substance on his face, and he won't eat anymore. what is wrong with my Betta?
He is highly likely to have a fungal infection. You need to do something to your water. Change it regularly and maintain the right parameters. See the water parameters in the comment section of the article. You can also follow the Bettafix Remedy link in the article to get the medication.
Helpful 1My betta fish has a little white ball next to his nose and close to his eye. It looks like a tumor. I'm getting worried about what it could be! I've had him for more than three years already, and he was doing just fine. He still eats and sleeps like normal. Today was clean up time for his tank, and I noticed that ball next to his nose. Any ideas about what it could be?
The water was getting too dirty, and this could have caused the problem. Go on to clean the tank and maintain the right water parameters. See the parameters in the comment section of this article.
Helpful 3Three of my bettas died of dropsy a few days after a water change. This seems to be a pattern, but I don’t know why? I have a filtered tank and change 100 percent of the water once a month.
Dropsy is deadly, and a 100 percent water change is also not so good. I would recommend you change 50-75 percent of the water just to save the rest.

AUTHORYeah, if the spots are loose and you can easily remove them, then it could be some tiny sand particles getting in the small scales on the face. It could also be a fungal infection which can be dealt by changing the water frequently.
I've noticed that my white betta has developed black spots all around his face, is this normal? I've had him for a year and he's still just as energetic and interactive as he's always been - no changes or sign of sickness. I do have black sand as the substrate, could that becausing it?
- AUTHOR
Well, if he improving well, then the spot could be a harmless body mark, but you need to keep a keen eye on it to see if there are any changes - like change in size, color, etc
So, I looked at my betta fish and saw a tiny spot on his head. It's not a white spot though. He had grown lethargic recently, so I changed his water and fed him the next day. He seems to be doing better since he's swimming a lot more and eating well. But I am still concerned about that small spot on his head. It's not bothering him, but I'm just curious as to what it could be.
- AUTHOR
@Mitchell. You can try optimizing the water parameters - ammonia, nitrates, nitrites, pH, etc. See all the parameters in the comments below, and also their allowed levels.
I had one betta (white opal) that died after his fins got red at the tips). Now I have a 2nd betta (different bowl, etc.) that’s not acting right. Took him out and cleaned bowl. Doing better, but his white fins are now turning red). Ideas suggestions?
- AUTHOR
@SkittlesTheBetta This is highly likely to be the swim bladder condition or some stress due to the limited resources. Check the condition in the article and see how you can improve the resources.
My male betta hasn't been eating and he lays at the bottom of his tank. He is in a small tank, no filter, no heater and my mom wont let me give him proper housing. He's been like this for 5 days
- AUTHOR
If it is a small tank, then change water after every 5 days - at least 75% change. Sometimes you can try 100% water change. You can also try checking the water parameters - ammonia, nitrates, pH, etc and optimizing them. The other thing is to try the medications mentioned in the article - follow the Myxazin and Bettafix Remedy links in article.
Help! My fish has a few white spots and a big one by his tail. He isn't as active as he used to be. I clean his tank 1 a week but maybe I didn't do it well. I have betta conditioner but I use tap water should I change it to spring. I think he has Columnaris so please hurry and reply.
- AUTHOR
You can try measuring water parameter such as ammonia, nitrate, nitrite, pH, etc and keep them optimum. See all parameters in the comments below. You can also try the Bettafix Remedy mentioned in the article which treats a wide range of fish infections.
My beta fish has a white spot under his left eye and his eye swollen
So I start change his water spring water and I add two drops of special conditioner for the water I have four days since change the water he still have it but smaller but I'm worried about his eye is swollen.
Thank you soo much if you could please advice me wat else could I do
- AUTHOR
Small amounts - less than 50g/day.
how much do you feed beta fish?
Thank you so much for your answer, I know you must be very busy! His fins and tail look ok I think...Top fin looks sort of constricted (wish I could post a picture). He likes to eat - will come up/eat and then dive under his leaf again. Is there something I should administer that would not hurt him and possibly clear up anything he may have? Thank you for saving fish!
- AUTHOR
@Aireana It is not possible to attach a photo here, but I recommend that you monitor his progress to note any changes. Fins and tail should be full and vibrant, and with no abnormal spots.
Hello,
I have the cleaning & temp of the water right but the PH continues to be high. I use purified spring water in the gal jugs and have been adding a water conditioner.
My betta has a white spot on his lip that I thought maybe a fungus. I treated with tea tree oil for 5 days and seemed to get smaller. I am not sure if the tail/fin is normal or not - may I send a picture? Thank you so much!
- AUTHOR
If he doesn't show any signs of sickness, then it is highly likely to be a birthmark.
My betta fish has a blue spot when he is all red what does that mean?
- AUTHOR
It could be some issues with the water. You can try changing it more frequently, condition it and maintain the right water parameters - ammonia, nitrates, nitrites, pH, etc. See all the parameters in the comments below. As for the conditioning, you can follow the Bettafix Remedy link in the article to find the API Aquarium Salt Conditioner.
Hi! My betta had a whitish spot near the fin that has been growing and already took almost half of his body. Also his tail seems to be degrading. I already tried to treat against bacterial and fungal but without success. His behavior seems normal. What can it be? Thanks!
- AUTHOR
It is highly likely to be a fungal infection or worm. Just check it carefully, and if is fungi, you can get the Bettafix Remedy mentioned in the article. If it is a worm, you need to change the water, clean the infected part of the fish and apply some disinfectant.
my beta has a bump on his side. It looks like a piece of white it coming out of his scales.
- AUTHOR
He may have the swim bladder condition. You can increase the water temperature, feed him cooked pea and make him eat less and then condition your water. See this conditioner - https://www.amazon.com/gp/product/B0010P0ZJK/?tag=...

White lumps are usually fungal, especially if they are soft and loose. Change water regularly and maintain the right water parameters. See the parameters in the comments above. I also recommend you get the Bettafix Remedy mentioned in the article to treat your fish.
my fish has a giant white lump on the side of his head
- AUTHOR
If he has some sores, you need to keep the water clean and if possible disinfect it to kill harmful fungi and bacteria they may enter his body.
I just rescued my betta fish after he got stuck in the water filter. It's been a day now and he is very still, swimming at the surface of the water, and blowing bubbles. It appears as if his head and back is injured, as he was once completely blue and now those areas are pinkish grey. Is there any way I can save him?
- AUTHOR
Well, a photo could help, but if the lump is hard, it is highly likely to be a tumor. Otherwise it could be an internal swelling caused by bacteria, virus or fungi.
As for the grey color, this could be velvet. You can try changing the water and maintaining the right parameters. You can also get the Bettafix Remedy mentioned in the article to help with the infection.
My male Betta has a lump or what looks like tumor towards his tail,purtuding on both sides of his body. He doesn’t swim,floats wierd and has almost grey on his chin(? Not sure what that part is called) what could this be?

This is highly likely to be an early sign of velvet. You can try changing water more often and keep the water parameters right. See the parameters in the comment section of the article. As for the treatment, follow the Bettafix Remedy link in the article to get the medication.
Before doing current research on bettas I went out to buy two female bettas for my male betta as I had learned along long long time ago that it was the only dynamic they would do well in. So as I was slowly trying to get them accustomed to one another (before my current research) I was having them in the same tank. Obviously it didn't work out so that's when I found out that this was not an ideal social setup so I separated them. I don't think my females were sick when I bought them but now all three of them seem to have similar signs of illness that I noticed only after I started feeding them bloodworms. They are all acting fine with no change to their behavior however they have physical marks on them that were not there previously. They all have what seems to look like two slanted very pigmented red scars near their gills on both sides of their bodies. There is a more noticeable underlying redness to their faces, no swelling whatsoever. So I don't know if this is an illness or not, or if it's due to their tank, to the newly introduced bloodworms, or something else. Seeing the stuff on the list gives me a couple options of what it can be but they don't show any other signs of those illnesses. It's just the redness that is the only factor in those illnesses. So I am still lost as to what it could be if anything. Any help would be so greatly appreciated, thank u.

My white betta (unsure of the gender) has red on the top of their head, almost like a rash, I've had it for about..3-5 months i think. It's also a bit unresponsive sometimes when i feed it, I use Wardley betta food, they are small pellets.Its been there for a few weeks and they're also a bit pink almost, I'm really concerned. Any clue what any of this could be?
- AUTHOR
Well, if he looks pretty normal - no signs of sickness, then it is highly likely to be nipping.
On the other issue, white spots are usually fungal. You can follow the link in the article to get a Bettafix Remedy.
For the past 3 days my approximately 6 month (we've had him for 3) male veiltail betta's caudal fin has started to look very ragged, to the point of becoming stringy from chunks missing. folks who see the photo say he is nipping (wish i could show photo). How do you differentiate nipping from fin rot? Columnaris? If he is nipping, what do we do? 3 gallon tank. Water parameters are all good. Temp 78 degrees. Moss balls. Artificial plants. 1 Nerite snail. Always keep a couple small Indian Almond leaves, low dose of aquarium salt.
Also just noticed small white spot on his left gill cover, size of single scale or so. Definitely new.

Hi,
My betta fish has fins rot. I have tried everything: change its water frequently. Used bettafix. The stopped it since I read it does not work. I also used JFC tablets, but I don’t see any improvement in the fins. He eats well and swins and rest normally, but I don’t see its fins recovering. What else can I do? Please help
- AUTHOR
Like I have answered in the Q&A section, if she is not showing any signs of sickness, it is highly likely to be a developing bodymark. So don't worry, but keep a keen eye on her to act immediate in case it's not a mark.
My new betta I got had a small red spot on top of her head. I have her in quarantine before I add her to my sorority. I can’t tell if the spot is still methgoing by that needs to be treated. I can’t tell if it’s just a scale though. Should I treat her and what for?
- AUTHOR
If she was fine hours before, then it is likely that she was bruised by a sharp object in the water. You can disinfect the wound and keep the water extremely clean.
female beta has what looks like a large bruise on her side after mating she was fine before. this was only about 4 hours after mating she is staying on top of the water and does not look well what can I do?

Try Amazon. Follow the link on the Velvet section to search for medication,
I took a betta fish that was living in a small glass and put it in a brand new 5 gallon tank. Treated the water, washed everything with water, got a heater, thermometer and pump. I transferred him to the new water over several hours. Have added new water. He eats the pellets for betta but not the blood worms. He was raggedy to begin with but his eyes may be out a little. Did not notice them at all before. Today is Day 4 in the 5 gallon tank. I don't have plants because the pet store guy made a big warning about snails taking over the tank.
Possible pop eye and shredded fins are my issue. Where would you get the medication indicated above?

@ Try maintaining the correct water parameters (see them in the answers above) and consider some good medication (see in the article).
My Betta is a half Moon male and for the past two or three months his fins and scales have been fading, along with his gills turning white. I've tried everything from changing his water often to feeding him once daily or every other day, and nothing seems to be helping. I don't know what to do.
- AUTHOR
If it was all due to constipation, then you just need to keep feeding her accordingly. May be you try softer feeds and avoid overfeeding.
My betta has been swimming sideways for weeks and stays to the bottom of the tank. I have moved her into a smaller tank, didn't feed her for a couple of days and fed her the insides of a pea. It doesn't seem to help, other that she seems fine. I do feed her every other day as I'm sure she was constipated. is there anything else I can do for her?

@Michelle. Highly likely to be velvet! Try the Betta Remedy mentioned in the velvet section.

Sounds like he has a combination of ailments! Read carefully the diseases and their symptoms!
My fish is very sick. He is not eating, moving very little, whit bubble on and bellow one eye, color in tail is draining, the tail is ripping, I'm worried.

The pic would have helped, but your betta could be suffering from more than one ailment! The rough body could be due to velvet while the sores could be a sign of columnaris or furunculosis. You can try medications with antibiotics, and also fungus clear.
My betta has started to hide all day (in his little house) when he used to show excitement when I walked in the room and doesn't appear to be eating. His body looks rough and porcupine like. He also has sores. Recommended by the fish store, I added aquarium salt and bettafix. This has been the case for a few weeks and he doesn't seem to be getting any better. Any thoughts? I also have a photo.

@Liz If the buildup was cotton-like, then it's most likely to be Fish Fungus. See the medications for this condition in the article. Concerning survival, I think he has a chance given that the hole has been there for days. If it was something serious, he would not be living by now! In addition, most fungal infections happen due to dirty conditions, so keep changing and conditioning water and also maintain the right parameters - see them in the answers above.
Hi, I've been doing research trying to figure out what my betta has, I was hoping you could help. He started out lethargic, and having trouble breathing, and I noticed an off-white buildup in his gills on one side. I thought it might be scar tissue or gill hyperplasia, so I did a water change with aquarium salt and started treating him with Bettafix. It appeared to be clearing up, but he's still having trouble breathing and now there's a huge hole in his side where the buildup had been before--I can't see any obvious parasites, and the hole isn't bloody so I don't think it's furunculosis. It's just hollow and white and kind of wispy, or maybe I'm seeing bones? I panicked and started him on Tetra Lifeguard All-in-one last night, but I'm really doubting that he's going to survive. Do you have any idea what this disease could be? It doesn't look like any of the ones listed here (but maybe I'm missing something), and I want to know if there's any chance that he can be saved. Thank you!

@Jay In addition to cleaning the tank, change the water regularly and keep the right parameters - see them in the answers above. Concerning the medicines, you may need to use some more effort in searching for them. You can check on Amazon India.

@Jasmine It's most likely to be her color, but keep the water/tank clean and with the right parameters - see them in the answers above.
Hi There , I am a new owner to Betta Fish I have one male and Female betta . I have looked at the above and wanted to ask if someone can help me on my small Female I bought her a few weeks ago and decided to do a dip just incase there are any infections as her anal fins seemed to be torn or rotted away. when I shone a torch to check for any viral infection nothing appeared on the body but only on the outer corners of her fins Like a Blue Glow ? is this perhaps the colour she may turn into once she has grown or is this some type of infection? its basically like a neon glow on the outer rims of the fin
