Betta fish suffer from a number of health conditions, but the good news for keepers of this 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, as well as their prevention, diagnosis, and treatment. If you keep Siamese fighting fish at home, read on to learn how you can keep your aquatic pet healthy.

Betta fish diseases and illnesses can be categorized as fungal, parasitic, or 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

  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 tails of betta fish. 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 survive 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 or clumps around the lips and mouth of the fish.

It can be avoided by keeping the water clean, i.e., changing and conditioning it regularly.

Amoxicillin as an antibiotic can cure mouth fungus. Other medications that cure general fish fungus (described below) can also help with the infection.

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 that can also appear on the fins and tail.

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, white fuzz films, slime (mucus), or white lumps and bumps on the skin.

It can be prevented by avoiding primary infections and injuries and keeping the aquarium clean, i.e., changing and conditioning the water regularly.

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 fish infected with velvet appear to have a rusty skin and scaly head including the gills, and can have black spots allover the 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, rings, or spots on the belly, fins, tail, gills, and other parts of the skin of betta.

It can be prevented by changing and conditioning the water regularly, and also optimizing parameters like ammonia, pH, nitrites, and dissolved solids.

The sickness can be treated by Fish-zole, Malachite Green, salt baths, or the Bettafix Remedy mentioned above.

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.

Anchor worms

13. Hole in the Head

Betta infected with hole in the head have an abrasion on the head that looks like a pinhole or white fuzz.

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, growths, 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.

Moreover, betta fish can suffer from fading color or abnormal color change, and can develop things like bubbles and solid particles on their bodies. These conditions can be controlled by changing and conditioning the water regularly, and also optimizing parameters like ammonia, pH, nitrites, nitrates, air, water hardness, water temperature, and organic matter and dissolved solids.

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?

Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.

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.

  • My new Betta fish, that I got from Walmart (so you know it was in horrible conditions before I got it) is now gasping at the top of the water; he flares up anytime that anyone comes around him, he's not swimming like a normal Betta fish does either. He's my baby brother's fish, and he would be devastated if it were to die. What can I do to treat him?

    It looks like you have fed him a lot, and as a result, has developed the swim bladder condition. See how to deal with the condition from the article. He could also be under stress because of the new conditions, so you can also wait to see if he'll get better.

  • 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 fish is pale and is alive but at the bottom of its tank. What does it mean when a betta fish remains at the bottom of its tank?

    Highly likely that you are overfeeding him and has developed the swim bladder condition. See how to deal with the condition from the article.

  • My betta fish is not moving much and is lazing around on one side of the tank. Its fins appear to have become stiff. What is the cause and cure for such a condition?

    It looks like he's being overwhelmed by the conditions of the water. Try changing and conditioning the water, and maintain the right levels of water parameters - pH, ammonia, nitrites, etc. See all parameters in the comment section of this article.

      i bought my daughter a betta a couple weeks ago. Ive had bettas before but never had to deal with any skin/fin ailments. This otherwise active. bright blue betta, Sky, developed tiny red dots that resemble the red betta food balls.Sone look like they're sitting on his skin, others arent as raised. They are mostly on his tail but some on his underbelly fins.Weve been treating the tank with Bettafix. The fishstore said that it would treat most fungal, bacterial or parasitic problems but they also advised to me that they arent veterenarians. The dots dissipated but during the 7 day treatment, they reaappeared. Any advice?

      @Crimson you can see how to deal with white spots from article, but as far as eating is concerned, it looks like he has the swim bladder condition and can therefore go for days without eating until the condition is gone.

      My fish Crimson just recently got over dropsy we have taken good care of him but now he seems as pale as he was when had it but isnt bloated and has this white spot near his gill. He barely eats and it gets hard to feed him. I uavent fed him for a while and not on purpose he just wont see it or realize its there.

      I have diagnosed my Betta to have swim bladder disease. Have fasted for a length of time. Still swims funny but has the will to live. Finds locations to stay at the top of the tank otherwise unwillingly floats to bottom. Problem I am having now is he won't eat. Have tried his pellets, frozen bloodworms and peas. He is not interested. He has been fasted now for 2 weeks. What else can I try?

      my beta fish is a female and shes smaller than usual. when i got her she was bright blue and turquoise, now maybe 3 weeks later, the very tops of her fins are turning brown along with the area near her gills, the brown is getting worse but only by a tiny bit, I've noticed shes inactive lately too. I've cleaned her tank and watched her more, but still keeps happening, i don't know if its the food I've gave her, but i doubt it, .my friend who is a fish expert told me this is the best food. i feed her a little in the morning and a little at night.

      i have never had a fish before and this is my first one, could you please help me find out whats wrong with my fish please?

      also if this one were to pass could you recommend me a fish that is easy for beginners, like me?

      He might have been hurt by the other fish, or even bruised by objects in tank during the chase. If this is the case, he will get better with time. But you can use some disinfectants to keep the patches free from microorganisms.

      Some fungal infections appear grey, so don't rule out these types of infections. You can just monitor him closely to see how the patches will develop.

      Most spots are usually fungal and can be treated with medications like Bettafix Remedy (see it in the article). Others are parasitic like ich - see from the article.

      As for the losing color, it could be due to poor water conditions, so you can try changing and conditioning it regularly, and also optimizing its parameters - pH, ammonia, nitrite, dissolved solids, etc.

      I have the most beautiful Betta. When I got him 6 months ago he was sociable, highly active always cane to the glass to meet me and would stay as long as I talked with him. He never hid from me and would flare and blow bubbles all the time. I literally just did a 30% water change in his 5.5 gallon tank. I also cleaned decor and put it back exactly where it was. Now I’m completely freaking out he’s swimming with clamped fins, jerking through the water and I found him up against the filter. And he’s hiding from me. All of these symptoms are completely alien to this guy. I conditioned the water, waited, added the appropriate bacteria and put some H2O drops in the water to reduce stress. This is the same routine I’ve been following with him and he has never behaved this way. Am I losing him? Please, please help.

      I just moved my betta into a bigger tank and now he is not eating, flaring, laying at the bottom of the tank, going to the surface to breathe, fins shrunken, and lethargic. He also seemed to hide near the filter when it was turned on and roll sideways. What do I do?

      @kdsankar Not really. It's only that your tank is highly likely to be harboring the dropsy-causing bacteria.

      Is "Dropsy" Infectious?

      Because i have 3 male bettas in same tank, Two betta died as same. And my 3rd betta is also showing the same symptoms.

      It is likely that you have overfed her and has developed the swim bladder condition. See how to deal with the condition from the article.

      @Colton It could also be slime which like fungus can be aggravated by dirt water. So try changing the water regularly and keep it clean.

      My Betta has some white cotton-like fluff hanging from his fins. I’m not sure what exactly it is, but my best guess is some kind of fungus. He came with it and we have been fighting it for several months, but we can’t seem to curb it entirely. We have been giving him Jungle Fungus and putting a small amount of aquarium salt in with water changes but the mystery fungus just persists! It doesn’t seem to alter his energy level as he still zooms around with as much energy as ever. Any insight into what might be going on and what we permanently knock this fungus out for good?

      @Sandra I think you are doing everything right. Most of the symptoms you see are just out of the pain of the injury. Some times fish can go for days without food, so this is not a big issue.

      May be you can change the water regularly to keep harmful bacteria away, and try to disinfect the wound. You can also try keeping him off the sharp/rough objects

      Hello, I have a veiltail betta fish named Scottie and he is not doing very well. He was the only fish in a 5 gallon tank with a heater, a filter, some artificial plants and a hiding spot. He was doing fine until Dec. 9. Scottie doesn't like to come out of his hiding spot after dark, but my sister wanted to see him, so she shook his tank and spooked him.

      That was on Dec. 9, and i only found out that she did that 2 days later because someone told me. The edges of the inside of his hiding spot were sharp, so when he got spooked, he cut himself badly. After that, he was lethargic and hasn't eaten since(i feed him betta pellets by the way). It's been 9 days so far and he still hasn't eaten. I recently moved him into a smaller tank so he could reach the surface easier to get air. Now he is still lethargic and stays at the bottom of the tank, but at random times, he darts around crazily. His injuries seem to have cleared up a little, but every time he swims up for air, he just sinks back to the bottom. He seems to be breathing heavy sometimes, and he is still not eating.

      Sometimes he swims a little bit at the bottom, but then he stops and lays against the side of the tank or the gravel, or on one of the Luffy betta balls in his tank. This was originally my sister's fish, but she wasn't taking care of him. His water was filthy and he was in a bowl. No heater, and a bubble over his eye. So i've had him for about a year now, gradually learning how to properly care for a betta fish, because I didn't really know either. I just felt bad for Scottie. He was doing good until she came over and scared him last week. She didn't buy any necessary items for Scottie except Start Right water treater and pellets, so I bought him a heater and filter and larger tank and decorations. I plan to buy Aquarium Salt, Melafix Remedy, and some live plants instead of fake ones(so he won't hurt himself anymore, IF he makes it through this) this Wednesday to see if that helps Scottie. I don't know what else to do. Please help.

      I lived in Taiwan and then American and I followed all the procedures that are needed for keeping bettas. I did 20% water changes I use a little bit of aquarium salt, water dechlorinator I have a tank that's at least 3.5 gallons. I have a life plan to place for them to hide. I have a low flow filter for one of my tanks and the other two I need to switch over because maybe the flow is too strong but only on one of them. Now I have pellets in Taiwan they don't have blood worms and flea eggs. and absolutely no products from Omega one.

      But in the last three months I've had for betta's died and 6 Guppies...... what killed the betta's most likely fin rot but my last betta it had a filter but he didn't die from fin rot I don't know what he died from he just lost his color and died.

      now living in Taiwan they say all the opposite. They don't need a filter because we're supposed to do 20% water change. they need a heater but they need me no more than half a gallon tank.

      I really don't know how to keep my betta's alive. I just bought a beautiful Orange County jail for the equivalent of 5 US dollars so I'm going to keep him in a half gallon tank what the life plant and heater and see how that works. I put in the dechlorinator and a little bit of aquarium salt with aloe Vera. Plus you'll have a light so the plant can get with it needs and I'll put one drop of plant food in. I really don't know what to do. I've got a red veiltail he seems to be doing fine now the tip of his tail turned gray a little bit I don't know if he was feeling stressed because maybe the filter was too strong. but my little baby she's in like the equivalent of a 1 gallon glass aquarium she's got a low flow filter and heater. I was afraid if I got her something bigger it would kill her. ..... but the small pet store that I went to they've been raising fish for 20 years and all their betta's look really good it's sort of like Russian Roulette.

      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?

      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.
