They are insectivores and should be fed a proper diet if you want them to do well. The basic rules for keeping any fish successfully are as follows. 1 inch of fish must have at least 1 gallon of water. (A Betta is a 3 inch fish) Every tank must have a permanently running 'cycled' filter. Every tank must have at least 50% of its water replaced every week. Betta food is available at most pet shops. A feed of live brine shrimp or mosquito larvae once a week will also be very good for them.
