Why is my male betta making bubbles and not eating his food?

This is normal behavior and no cause for concern. A Bettas bubble nest is unique to each fish in size and pattern. The fact that he is building one is a testament to his recovery and improved health. A sick Betta will not build a bubble nest.

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.

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 chemistry and water temperature. Aim for 0 ppm ammonia and nitrites with nitrates 30 ppm or below. Water temp should be between 78 F and 80 F. Add only plain aquarium salt (NOT table or Epsom salt). Add no more than 1 teaspoon per gallon and treat for 10-14 days. Lower the water level by half to make it easier for her to reach the surface. Bettas can breathe room air if necessary. Soak pellets in some garlic juice to stimulate her appetite.

Hello, I recommend checking water quality parameters first for any fish displaying abnormal behavior. For starters, I'd recommend keeping your fish in a larger tank as it is much easier to keep the water clean over time. This website is a good reference for basic betta fish care: https://bettafish.org/care/ I hope this helps. Thanks for using PetCoach.

The ideal water temperature for bettas is between 78 F and 80 F. Check water quality and perform a partial water change if necessary. Used aged or conditioned water that is temperature matched to prevent shock or stress. If he won't eat pellets, try soaking them in a bit of garlic juice. This can serve as an appetite stimulant as well as an immune system booster. You can also offer freeze dried (or live) bloodworms, brine shrimp or tubifex worms. The "wiggling" when he swims may be normal for him but check his fins for signs of fin rot which can make swimming more difficult.

Thanks for reaching out about Felix. Any chance of ingested rocks or other material that can block the throat? Enlarged organs (goiter, heart) can also make swallowing difficult. A veterinary visit is probably needed to assess and provide a diagnostic/treatment plan. Good luck.
