how to care for a betta fish
Bowl or Tank. While small bowls are sold in pet stores for betta-keeping, providing at least a 10 gallon tank -- complete with heater -- for your betta is a healthier environment and probably will add to his life span. Keep the tank temperature between 72 and 80 degrees Fahrenheit, and the pH level between 6.8 and 7.4. A few live plants in the tank, such as java fern, provide an area for your betta to hang out. While you can keep betta fish in a tank with other, compatible species, that doesn't include other bettas.
Feed your Betta daily with freeze dried blood worms, brine shrimp, or an appropriate Betta food. They are omnivores and require meat to survive. They cannot live off plant roots. Feed your fish once daily up to 5-6 days per week.
