I have 2 zoa colonies and for the past 3 days they havent been opening as full as normal if at all. I noticed this morning both colonies have very thin things growing out of them with a tiny ball at the end of each one I think you can see them in the pics but took them with lights out so there are alot of shadows any ideas what these might be and if they could be the irritation. Should I dip them in coral RX? The last photo shows the 2 zoa locations one top left and the other bottom left, any help would be great. Tank parameters are as follows. Thanks all
