How long have you had it up and running?
I've got a very similar setup at work. I don't have any fish in it yet, just some shrimp and corals.
How's the cherub doing in yours. This is really too small a tank for him. Same goes for the tang in the 30 gal. I've been watching a cute one-eyed cherub that's been at the LFS for quite a while. I was considering him for my home tank, but the flameback I've already got would probably beat up on him so I haven't gotten him. My 40 has a friggin fish-killing crab in it, so I'm not putting any new fish in that one until I manage to capture it. Problem is there were 4 chomis, he's got 3 of them. I don't think he'll go after the bait in the jar while he's still full off my fish. :evil:
