I dont think so :-s. But I'm no expert tho . I have 3 right now. When they're in the 75 with my dats and bichirs, they dont have any patterns or stuff. Just a dark brown. Sometimes they color up a bit. But when I moved one to a 10 with my 6" gars. He showed great patterns! Will try to get pics tmrMight one of them be a Royal Nile?...I was always unclear about those.
