LOcal Asian supermarkets sell frozen food............Popcorn shrimp, krill, silversides, sardines, silverfish, and shrimp of all sizes..................$20 dollars worth of this stuff literally can feed a monster tank for a month..........Breeding your own feeders also saves money...........COnvict cihlids, guppies, swordtails, mollies are popular feeder breeder............The convict cichlid can be bred 3x's a month.......Twice a month is reasonable.............Each spawn will hatch out between 80-300 fry............A separate tank(20-55g) is best in raising the fry separately......................
