How Do You Take Care of a Betta Fish?

Betta fish eat once a day, often preferring to eat freeze-dried brine shrimp and blood worms. For optimal health, clean the fish tank once a week, and keep the top covered, since betta fish are known to jump out of their bowls by accident. Betta fish often like to have a plant in the tank with them. Properly cared for betta fish can live up to two years.

Male betta fish are highly aggressive and cannot be kept in pairs or groups in the same tank. Female bettas are less aggressive but still come into conflict with the males; however, two females can be encouraged to get along well. Betta fish can be very gentle with other fish species and do well when placed with a few other non-aggressive fish.

Food should be kept as fresh and clean as possible. Do not let uneaten food rot in the tank or provide unclean live food, as this can poison or even kill betta fish. If you are feeding live worms, make sure they are still in good condition. If you are keeping a plant in the tank, keep the leaves trimmed, and remove any rotting leaves. Wash any gravel thoroughly to remove accumulated debris. Do not place the tank near any direct sunlight, and keep the water temperature as even as possible. Betta fish prefer temperatures between 70 and 80 degrees Fahrenheit.
