I have never seen GUNK come out of mine, but it shrinks and shrivels and then blooms again.

Right now I am freaking out....mine moved in the tank, looks like it is purging, won't eat, and the mouth is wide open not all tight and puckery......I dont' know if they will eat or not when they purge but I am freakin man......

My clown keeps putting the bubbles in his mouth and then letting them go, he is not tearing them. Weird
