I recently got a small octopus and put it into my 55 gallon hexagon tank. I saw an immediate problem, it was 2 inches long! I try to feed it with a stick, but it is a nocturnal hunter, coming out late and is so small, it is rarely spotted. My question is, how do I feed something I can't find, in such a large tank, what should I feed it? It will eat frozen krill, but that is always to big and I can't put a small enough piece on the stick. I think it is a common Vulgaris, I would send you pictures..........but I can't find it!
