I currently have 2 red eyed red tailed puffers (1" and 2"), a south american puffer (1"), 2 flying foxs (both 2"), 8 tiger barbs (all 1"), 4 khuli loaches (all 2") and a clown loach (1"). I wanted to buy a polypterus senegalus, im aware thats its predatory so i wanted to know if it would eat any of the fish i currently have? The polypterus senegalus in the store is about 3-4".
