So I have noticed that my Acros are still not doing so hot... I looked very closely at one of the ones that seems to be RTNing and saw that there were these small white stringy things coming in and out of the polyp location... Like some type of worm or something that is sticking out a fan type thing to catch some food or whatever. What the heck is it? I think something has burrowed inside the acro or maybe several of them. Can I get rid of it somehow? I have given the acro an iodine bath and removed a crab from it, but I don't know what else to do to save it. It is a nice mini colony of acro....:sad:
