hi. just wanted to ask a couple questions about live coral. I recieved one from a friends friend and she said it needs no special care but had to get rid of her tank due to her moving, it looks like a rock with little "flowers" all over it and its green but a couple of the "flowers" seem to be dying. I have had it about a week. In my 55 gal tank i have lined with crushed coral and have had it in operation for about a year. I have 3 anemonies, 4 damsels, a blenny, and a crab. I feed them a standard marine flake in the morning, and frozen Krill at night and Kent Marine Micro.Vert (1 1/2 tsp.) 3 times a week. Is this not suitable for the coral? any help would be appreciated with my thanks in advance.
