I got these zoas a few weeks ago, dipper in Bayer and they've been doing great. The last few days however, I've been noticing these tiny black and white bugs crawling around on the frag plugs. I redipped a few yesterday but found a bug on another frag plug today, so I'm trying to get an ID for if this becomes a problem. The zoas are all still opening and happy, there's no tissue damage and I have yet to see the bugs on the actual corals themselves, just the plugs. They move very slowly and shmear away like a slug would, and are not your typical zoa eating nudibranch. Tried to get a picture but it's very tough due to their size and color. The bug is circled and on a speck of coralline. They definitely are not pods.
