I have a small fruit loop frag with about 3 polyps.For some reason they don't want to fully open which I think is weird because my other colony of zoanthids are doing phenamonal .I get my water tested by a buddy and said everything was good . Any one have and ideas what's wrong .oh I've had these in my tank for about 2 months lighting is 4 T5's and 1 250w metal halide .halide is only running 3 hours a day and its a 60 gallon tank .
