Right now I've got 7 tanks up and running and I just got 3 more that I'm going to start cycling pretty soon. As for fish all I got in my sw tank right now is a dogface puffer. In the fw tanks I've got a jardini arowana, a senegal bichir, an ornate bichir, a lima shovelnose catfish, a midas cichlid, a jack dempsey, a chocolate pleco, 2 spotted gars, a clown knife, 2 royal knives, 3 peacock bass, a ropefish, a tiger muskie, a northern pike, and 3 red-tail barracuda.
I'm always getting new fish though, so everytime you ask me the list is going to be longer. lol
