I purchased a purple based anemone about a week ago and it's been looking great! At night, when the MH's go off and only the actinics are on, the anemone looks "deflated" and the it's tip look all flat with the mouth sticking out. I feed it regularly (bout once everyother day) and it takes whatever i feed it, mysis, brine, krill. Tank specs are: lighting is dual 400 iwasakis with 2 by 40w NO actinics all over a 75g tank. All water params are normal and everything seems to be doing ok. My 20 or so sps are doing excellent. During the day the anemone looks find though, should I be worried? It is about 6 inches from the top of the tank. What do I do?
