Cool right now I have an eclipse catfish and a bristlenose pleco. I love them! But the only thing I dislike is that my eclipse only comes out at night... Thanks everyone I am now considering getting some Cories! So I was thinking about 6. Does it matter if I mix up the species or will they all school together? And as of now all my fish are in a 45 gallon tank but I am working on getting my 150 gallon setup. I just put my sand and water in it today so I wont be able to put fish in it for a few more weeks. Could I keep the Cories in a 45 for now?
