Right now for fish I have a juvenile blue eye bristletooth tang, masuda hog, flametail blenny, and a tomato clown.
Tang aggression is the thing I'm most worried about at this point. If it comes down to it I'll probably pull the tang. He's been acting odd since I moved him from a 4' to 3' tank (lots of color changes, frantic glass nibbling) and he'll eventually outgrow my current setup (36x18x24, but he's about 2.5" now).
Edit: I also have an evil 4-line who's been living in the sump, but he should be going to the store's frag tank tomorrow.
