It has just about lost one mouth of about five, not getting good extension. It has been part of the general malaise that has hit some of my corals. I moved it from my 90 g to my nano tonight. I've got a few LPS in there and they are doing great so maybe that is a better environment right now. My clown is very unhappy but luckily it likes a couple of frogspawn in the big tank so I hope she's not too traumatized.
