i was on holidays for a few weeks and when i got back my xenia wasnt doing so hot. it was the size of a football (on a single rock) before i left and now its shrivelled right up to the size of a golf ball. All my other corals seem to be doing ok, i did a large w/c after i got home and that seemed to liven up the gsp which was a little lethargic but the xenia is about to kick it- any ideas?
