Hey if you are looking for tank mates you might want to ask Novice150. He has a 1500 gal tank (i think or something close to that) and he has a black tip and has spent a great deal of money experimenting with tank mates for a black tip. Most have become lunch or dinner some even breakfast, hehe. Anyway ask him what he has had luck with.
Great tank, I would love one, only I am a bit short on the funds. I guess I will sell my car and then we are in business.
