I'm keeping all of them. I was going to buy another 75 gal. But I've decided to build a tank for them. I'm not really convinced that I will have to move them anytime soon though. There growing fast but they all seem to be getting along fine. I had one problem when I put 2 Oscars in the tank with them though. The Oscars didn't make it. I bought all my fish when they were about a inch long. Now my largest jack, con and jag are just about 3 in. The Oscars were the same size but they got exicuted in about a week. Damn they were some good looking fish.
