I have a Marble Vail Angel, he is about 2" body and I have had him for about a week or two. My Mollies picked on him for a while (yes strange) till I took them out. Now he lives in my 36g with 6 Sepae Tetras and a Pictus. He pretty much has the place to him self. The tetras hang out near the bottom and never even acknowledge him. My question is, he is very still. He kinda hangs out in one spot all the time. Sure he will slowly swim around occasionally but he is rather inactive. I have no ideas about Angels so I don't know if they are normal active.
