I came home today to one of my bubble tips deflated. All my other corals look awesome just one of the three bubbles are deflated. I did notice my clown being over aggressive to my large bubble last night and caused it to close not deflate. Could my clown being over aggressive cause it to deflate.
Clowns have been known to kill BTA's if they are small (love them to death). They also deflate for other reasons, though. Some of mine deflate when it is close to lights out. If it does not bounce back the next day, I would blame the clown.
