2 of my zoa frags were not doing so hot for a few days so i decided to dip them last night in a mix of iodine and revive and over 20 spiders came out...... Should i just throw these frags out? It was completely infested and i know they only way to rid my tank of them is to keep dipping weekly. Pls lmk what you guys think and lmk if this is the most spiders youve seen on a frag. The frags only have about 10heads each... So thats 1 spider per head....not good.
