My betta is bloated with a dark spot, and peas didn't help. What's wrong?

By your description, there may be seversl issues here. Check the water chemistry and quality. Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Ideally, you want the following parameters: 0 ppm ammonia, 0 ppm nitrites, 20 ppm or less nitrates, pH around 7, water temperature between 78 F and 80 F. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent further stress or shock. Decrease the water level to make it easier for your fish to surface. Fast him for 2-3 days then feed bits of cooked and shelled green peas until swimming and defecation are normal. If he remains bloated, prepare a bowl of water at the proper temperature and dissolve 1 tablespoon of Epsom salt for each gallon. Allow for a 15-30 minute swim once or twice daily. In the main tank, use an antibiotic, such ad Kanaplex or Maracyn, to treat infection/fin rot. A conditioner such as StressCoat can also help fins. These products can be found in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Bump the temperature up to 80 F. The warmer water may aid in digestion. Continue feeding bits of cooked, shelled green peas until he is defecating normally and regularly. If internal parasites are a concern, PraziPro or General Cure (by API) may resolve the issue. PraziPro is safe for the snails. If you decide to use General Cure, it would be safest to remove the snails during treatment.

Swim bladder issues can be caused by bacterial infection or constipation. These reasons can be compounded by poor water quality. Use a home test kit or submit a sample of water for testing to confirm 0ppm ammonia and nitrites with nitrates at 20 ppm or less. Most pet stores will do this for free or for a small fee. Partial water changes can be done to stabilize chemistry and maintain or improve water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Bettas do best between 78F and 80F. Once you have pristine water quality, fast him for 3 days. Resume feeding bits of cooked and shelled green peas until defecation and swimming are normal again. If this doesn't help, consider a broad spectrum antibiotic. You can find one in the aquarium section of the local pet store. Look for Furan, Maracyn 1 and 2 or Kanaplex. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Check water chemistry first. Use a home test kit or submit a water sample for testing. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20 ppm or less. Perform a partial water change to stabilize water chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78 F and 80 F. By your description, the issue may be swim bladder disease. This can be caused by infection (bacterial or parasites) or constipation. Maintain water quality as described above. Fast the fish for 3 days then resume feeding bits of cooked and shelled green peas. This will help with constipation. If this doesn't help. you can get a broad spectrum antibiotic from the local pet store. Look in the aquarium section. Follow label directions carefully and remove the carbon filter insert during treatment.

Check water quality using a home test kit if you have one. If not, bring a water sample to the local pet or fish store. Either may test water for free or for a nominal fee. Confirm 0 ppm (parts per million) ammonia and nitrites. Nitrates should be 40 ppm or less. Partial water changes using aged or conditioned water can be done to improve water quality. Many times poor water quality can lead to stress or infection. The symptoms described may point to swim bladder disease. This can be caused by infection, constipation, stress or parasites. The red rash may indicate infection. Fast your fish for 3 days then offer bits of cooked, shelled green peas until they are swimming and defecating normally. A product such as Maracyn or Kanaplex may treat infection. You can purchase either (or generic antibiotics such as tetracycline amoxicillin or erythromycin) in the aquarium section of the local pet or fish store. Follow label directions carefully and remove the carbon filter insert if indicated during treatment. Make sure water temperature is between 78 F and 80 F, this is the optimal range for bettas.

He may be dealing with some swim bladder issues. The swim bladder is what keeps a fish upright and controls buoyancy. Infection, poor water quality or constipation can affect the swim bladder. Perform a water change. Use aged or conditioned water that is temperature matched to prevent further stress or shock. My choice for conditioners are AmQuel and NovAqua. You can purchase them in most pet stores or fish stores. Bettas are warm water fish and do best between 78 F and 80 F. Anything below 75 F will be stressful. A small tank heater may be necessary to maintain proper temperature. Dissolve 1 teaspoon of plain aquarium salt (NOT table salt) per gallon of water in a cup of tank water and gently pour it in. This will act as a general tonic reducing stress, improving gill function and treating minor infection. Change the water daily to maintain quality and dissolve just enough salt to treat the water being replaced. Fast him for 3 days, then offer small bits of cooked, shelled green peas until defecation and swimming are normal. You can soak the bits in some garlic juice to stimulate his appetite and boost the immune system. Transition to a quality pelleted diet and fast for one day each week to maintain GI health.

Check the water temperature first. Bettas are tropical fish and do best between 78 F and 80 F. Next, check water quality. This can be done by using a home test kit or by submitting a water sample for testing. The local pet store may do this for free or for a small fee. Aim for an absence ( 0 ppm) of ammonia and nitrites with nitrates at 20 ppm or less. Perform partial water changes if necessary. Use only conditioned water that is temperature matched to prevent stress or shock. Offer an appropriate diet as well. Bettas are carnivorous, so make sure the flake or pellet is not mainly vegetable matter. Hikari makes a great Betta diet in pellet form. You can also offer blood worms, shrimp or Daphnia to add variety to the diet.
