Hi guys, got this tourch a couple of months ago and its been doing absolutely fine. Last week I returned from a short break away (about 4 days, had a friend call to turn lights on and feed etc) when I checked the tank all was well apart from the touch. The tentecals on each polyp seemed to be "short and fat" and two had shriveled up quite a lot. all water parameters are perfect and all other LPS are fine? During the past few days two of the heads are looking better but iv all most lost one and one more seems not so good? Any one know wats wrong? Is it a common issue with torches? Any help and advice would be great. Here's a pic
