with me it has been any small fish.... pretty much every type of baby cichlid.. guppy fancy and common.... rosey reds,gold fish,pinkies etc... ... i was for awhile getting african cichlids from a friend and feeding... i raised convicts for a month and fed the parents and babies... now i have nothing that needs them and any fish that does need them gets a choice in my house.... eat what a feed or starve to death
my own guppies raised on daphnia and bloodworms, and when the season is right, baby white suckers. all for a redfin pickerel in a rubbermaid. he's loving life.
