I have a comm tank ranging from rainbowfish to parrot fish and severums and a climbing perch ect. I notice they all go mad for brine shrimp, river shrimp and all other common livefoods. But lately ive been thinking outside the box and have been feeding crickets, moths and daddy long legs. I just wondered is that ok and what else is ok? Ladybirds? Spiders? Woodlouse? Small snails?butterflys? Caterpillars? Wheres the limit?
