My betta fish won't eat, isn't growing, and keeps floating. Help!
Try feeding Hikari Micro Pellets. The smaller size may make eating easier for him. You can also offer live blackworms as well as bloodworms. Confirm adequate water quality, proper water chemistry and adequate temperature. Bettas do best between 78F and 80F. If he is in a bowl or tank with no filter, weekly (or more frequent) water changes may be necessary.

How to care for a baby betta fish: tank, water changes, food, heat?
Mushu is very cute! Betta care is very easy. Ideally, a 5 gallon tank should be used to house your Betta. A smaller tank can be used, but the maintenance (water changes) will be much more frequent. A filter is always recommended otherwise water changes will be required every few days to maintain water quality. With a filter, 20% water changes can be done weekly or every two weeks. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Choices for conditioners include AmQuel Plus, NovAqua, StressCoat, Prime or StressZyme. A small submersible heater is necessary since Bettas are tropical fish. They do best in slow moving water between 78F and 80F. You can feed a pelleted diet such as Hikari Micro Pellets until he grows bigger. Baby brine shrimp, daphnia, bloodworms and blackworms can also be fed. Feed one or twice daily. He should only need 2-3 pellets at each feeding. The conditioners and food can be found in the aquarium section of the local P

My Betta fish isn't eating. What's wrong and how can I help?
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.

My new betta fish won't eat his pellets. Why is he spitting them out?
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 Boop by Petco.
