I don't have iodine or anything to dip them in and the boys are napping until 4...will just regular FW do anything? I pulled out the rock that I'm pretty sure had them (or at least has them now). The zoas on there haven't opened in about 2 days, but I was just figuing it was because I have to keep moving them away from that silly condi..Do I need to mess with the other zoa rocks since they are all open and full?
