I think my open brain coral ate my lettuce sea slug!!!! The sea slug went MIA the other day. He was alway motoring around munching my fields of hair algae and then puff just gone. He always seemed very healthy. At about the same time my open brain was all wadded up. I figured if the slug had die that brain was just reacting to the spike. However now I am thinking the brain ate the slug. For the last day or two the brain has looked all swollen up like after I feed him and now tonight he pumping out the brown strings. Since I haven't feed the brain in a couple weeks and everyone else in counted for... I guess thats the way it works on the reef.
