I purchased a BTA to host with my pair of black and white mis-bar clowns about a week ago. I put it in a 12 gal nano cube with a few LR. At first it wandered around looking for a place to settle but now it sits at the back of the tank kind of schriveled up and has a few black tips. Is it dying? my clowns have not gone near it. I HAVE A 35 GAL TANK WITH CORALS AND FISH. SHOULD i TRY TO PUT IT IN THERE OR IS IT TO LATE. I have a pair of perculas in the bigger tank so I suppose I can't put the other pair in there.. any advice would be appreciated. thanks ahead of time, I'm kinda new at this but don't want my BTA to die.
