Okay I'm so confused! I just recently started up a 55 gallon tank that I was going to make semi-agressive. I had 2 gold severums, and a pleco. I went to buy fish today and was told that I couldn't have this fish, that fish, the other fish. So I came home with a jewel chiclid and a convict...are they going to hurt the severums? And what could I add to my tank now if they won't hurt them? Was I led the wrong direction....I don't want any of them to get hurt and I feel like I just made a BIG boo boo. Can anyone help me out?
