Food & NutritionHow 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 Petco.
