i am thinking about purchasing a erythrinus erythrinus red high fin wolf fish. I have noticed lately on the forum a lot people think they have this fish, but actually don't. I am looking for the one with the nice red/orange on the dorsal and the body. What is the best wide to properly identify them at 2 to 3 inches (sorry can't wait until the wolf fish ID thread is done)? I saw four yesterday that i think are the erythrinus-erythrinus, but are not positive. Also I have read very mixed things on her about keeping more then one together in a tank. Would three be asking for a head ache? Thanks
