Hello, I have a 13.5 soft coral tank and I bought about 6 zoas about 2 weeks ago from tidal gardens and they were open and nice on the first few day and open all the way then they started to close up and opening half way and also I do not does the tank a lot due to the fact there are only soft corals in there and right now in the tank I have 1 gorgonian, finger leathers, and pulsing Xenia and GSP and some mushroom and ricordea and they all look good a happy and I wanted to know what is wrong with them? Sorry I do not have any pictures
