I have a 55g. I have a picasso trigger, who is extremely slow growing, and a foxface lo in with him. He just grew so fast. I didn't know that when I bought him. I figured I would be able to keep him for several years before he outgrew my tank. He's just getting too big. I was just hoping to find someone on here who was knowledgeable and would give him a good home before trading him into the lfs.
