I bought a green BTA from my LFS a while back and it's been remarkably healthy, but moving every night. I figured it was just adjusting to the light cycle/exploring the tank. Yesterday it found a nice crevice in the live rock and seemed to settle down, but this morning I awoke to find that it had been burned by the heater. The unburned parts look healthy, but the rest does not. My clown is nipping at some of the damaged tissue. What course of action would you recommend? I don't think it's going to die, but if it does, I know it can wipe out my tank. It looks like this now.
