I added some in with my cichlids a little while ago (oscar, severum, and acara). my cichlids are not particularly aggressive or large but they still ate 5 out of 7 of the roughly 3" pictus within a month. the two that are left get along great with my new jack Dempsey and flowerhorn though. theyre more of scavengers though. cant really compete with the cichlids for live food at feeding time.
I'm trying to find some ornate pims for my tank. methinks the pictus are too small to last when the cichlids are grown.
