First, I do not have a lot of experience with keeping a saltwater and am learning as much as I can as I go along. I got this tank a few months ago and it was already established. This soft coral in the pic seems to be really unhappy. I have tested the water and it appears fine. I have had the water tested and they also say it's fine. But this coral just never seems happy. Could it be the zoanthids growing out the base? Thanks for any input
