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

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.

There is certainly something wrong but unfortunately these signs are quite generic and would require a quite radical but logic approach to be interpreted correctly. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

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.
