Januaris is a supplier of pet food and care products, and he’s a true animal lover. He loves to write about dogs, bettas, bees, and pigeons.

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

  1. Fin and Tail Rot
  2. Columnaris
  3. Hemorrhagic
  4. Dropsy
  5. Pop Eye
  6. Eyecloud
  7. Mouth Fungus
  8. Furunculosis
  9. Fish Fungus
  10. Velvet
  11. Ich
  12. Anchor Worms
  13. Hole in the Head
  14. Swim Bladder Disorder
  15. 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 Waterlife-Myxazin manufactured by a reputable company.

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 Bettafix Remedy. Manufactured by Aquarium Pharmaceuticals, this medication consists of curing components such as sodium chloride, copper sulfate, acriflavin, formalin, sulfa 4 TMP, methylene blue and malachite green.

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.

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.

  • Why 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.

  • My betta seems to have worms coming off of it, and fin and tail abrasions. Could these be two different diseases that I need to treat?

    Yes, these could be anchor worms and probably fin and tail rot or columnaris. However, the abrasions could have been caused by sharp objects in the tank.

  • My male Betta fish is swollen, and he has what looks like an infection around his eyes. I removed the plastic plants and changed his water every five days. He will get a little better and then swell up again. His eyes were completely swollen shut. After frequent water changes and removal of plastic plants he is starting to recover, but today his mouth is swollen and a bit of inflamed. What can I do?

    You can try keeping the right water parameters. Check the parameters in the article section of the article.

      @WOLF It is highly likely that the water has some issues. It is either dirty or its parameters are not right. Try changing the water and maintaining the right levels of parameters - ammonia, pH, nitrate, temperature, etc.

      My betta fish has been sick for the over a week. He's been really lethargic, not really eating (he stopped eating completely for about a week, then eating two days in a row and he stopped eating again today), he either stays at the bottom or stays at the surface for really long periods of time and he has a lot of trouble breathing (you can see him breathing heavily). I dont really see any physical symptoms on his body but i was thinking maybe Oodinium ? I dont know what to do. I did a big change of water (about 50%) and then i keep changing it a little bit every few days.

      So I've had this betta for quite a few months and when I got him, his fins were full and perfect, but over the last couple months his fins have started to look like they are being nipped away. I know it's not fin rot as I've been monitoring him very closely and he shows no signs of sickness. I clean his tank regularly and make sure he's getting all the correct nutrients. Could he be nipping away his own fins or something else?

      If it's cotton-like, then it's highly likely to be a fungal infection. Other possibilities include worm and slime, but fungi is the biggest suspect. You can try keeping the water clean and using Bettafix Remedy mentioned in the article.

      Hi, my female betta we got as a very small fish about a year ago. While she has grown, about 5 months ago she developed a very large mass on one of her sides. Other than the mass she was fine for about 4 months, but a few weeks ago she bagn to always sink to the bottom of the tank or her cave and lay there all day and her coloring has begun to dull on her body. In the last few days she has stopped eating any foods. Does anything stick out to you? Are there any medications you would recommend or anything to do to help her?

      @Rrubicon, you could be feeding him excess giving him the swim bladder condition. As for water turning murky, there could be some objects in the water tank dissolving or decomposing releasing particles in the water.

      if the tumor is hard, then it's likely to be cancerous. if it's soft, then it can be a bacterial or fungal infection which can be dealt with the melafix you are using. Give it some time to see how it turns out.

      Yeah, 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.

      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.

      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.

      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.

      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.

      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?

      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.

      Anything to do with cotton or white mass is usually fungal. You need to do something with your water - change it regularly and maintain the right parameters. See the parameters in the comments above. You can also follow the Bettafix Remedy link in the article to get the fungal medication.

      My betta has a swollen eye with what looks like fungus or cotton coming out of his eye. He is very lethargic and not eating or swimming around. This appeared, what seems to be out of nowhere, a day and half ago. Can you please give me a recommendation of what it is, and what I can do to help him?

      Thank you

      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?

      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.

      Hello,

      My sweet female betta fish has 3 hard(looking), white bumps on her body. Biggest one on the top of her fin. She is acting perfectly normal, eating well , and the rest of her looks great. Good color, fins and tail look good.

      What could these hard looking, white bumped be? And how to treat?

      Thank you !!

      You can try keeping the water parameters optimum. Keep the right levels of pH, ammonia, nitrites, organic matter, etc. See the parameters in the comments above, and try to give him some time to see if there are any positive changes.

      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

      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.

      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.

      It is highly likely to be swim bladder or bloat. See the remedies for swim bladder in the answers above. As for bloat, just cut down on the amount of food you're giving him, but let the food feature some peeled pea.

      PLease HELP! My Betta is having issues and I’m very concerned for him, I’ve had him for 2years now and a few days ago I noticed him laying at the bottom of the tank, the next day he was still there and barley moving around. My boyfriend bought some medicine for him because he looks like he has tail rot but he might have another problem he looks really bloated and lays side ways and sometimes vertical and doesn’t look like he’s breathing. I’ll shine a light at him and he’ll swim up the the top get air and fall back down slow vertical again :( I don’t know what to do now.. I have him being treated in a little fish bowl and now using water conditioner.. he was in a 5 gallon tank when he got sick. What does this mean when he’s vertical could he have kidney disease or something??!? Pls help .. thanks in advance!!!

      He could have been pierced by a sharp object in the tank, but if the spot has a white area, it could be a worm.
