Definitely want to go with two butterfly fish. THough this restricts me now to aquascape the tank for the African region the butterfly fish come from. I usually do all set ups naturally to the region the fish come from and want to stick with fish from that region. Ok so I am going with the two African Butterfly fish, now this red wolf fish, is from where? I can't find alot of info on it since so many fish are mislabled wolf fish. How big do they get, what region are they from? And if it isn't Africa, I need a new fish to add with the Butterflys, I haven't checked on the chocolate Doradid yet but I love how they look. Anything with a decent size that can still be kept in a 30. (The 8'' 9'' margin).
