I got a buttercoferi a few weeks ago and was wondering if anyone here had any information on it. Usually I read up on a fish before I buy it but in this case it was a spur of the moment decision. So far this fish has killed my Oscar, Dempsey, Green Terror, and Frontosa which leaves it and a pair of female Convicts in the tank. I like variety in my tank but I need to know more about this fish before I waste any more money on fish that are just going to die when confronted with the buttercoferi. If anyone can give me a URL or the name of a book that has informaiton on this fish I would appreciate it.
