you know, I was looking at some pictures of the black clownfish, I think I might give it a shot and mix them with my tank-rasied clowns. I'll see how things go and keep you all updated. As for tangs, my yellow tang and my pacific sailfin tang will be moving into the 75 gallon, I was giving some thought to getting a regal tang, and when they outgrow my system I will move them into a bigger tank, which I figure it will be a good while before I have too. Also while we are on the subject of fish, what do you think about the stocking list for the 75 gallon tank, 5-7 blue/green chromis (I am wanting a nice shoaling pattern) 2 tank-raised clowns, 2 black clowns (maybe, just have to see what happens) 1 yellow tang, 1 pacific sailfin tang, 1 flame angelfish, and maybe a regal tang.
