Hi. I picked this up at my LFS. It was in their orphanage tank (random stuff brought in by customers). He said these are "low grade zoas". Can anyone get me a more positive ID. Also, how to treat/dip rock with colony? Also, should I just QT and inspect? Dip the whole rock to be safe? I'm just being cautious because I lost a bunch of frags to pests my last go round. I'm thinking about just dipping the whole rock in Bayer soln. in case there are any zoa spiders. Would this be a bad idea?
