We came home today and found my favorite goby, Sandy, had been eaten or swallowed by our brain coral. Poor thing, just her head was sticking out. When I moved the brain coral to remove Sandy, it seemed to spit her out. My daughter and I sent her off to the "heavenly sea", but I thought brain corals were okay with fish. We feed it with the PhytoPlankton every week, is this not enough? Thanks, Desiree
