Also! Earlier this week, when moving one of my zoas which I temporarily had on my rock near my GSP, I noticed there was something on the frag plug. Not sure what it is, it's been hard to ID. The things look like flatworms, but why would they be on the frag and not the coral? That's what has been confusing me. When I saw this, I dipped my coral in some dip and they came off with a blast from my baster. I set it back and next day they were back. I think I even saw some movement, very minor. It's been super hard to take a photo, but I finally got a good one when removing my zoa from that frag and away from that rock. I haven't seen them anywhere else, so it's just weird to me. It could have been algae maybe? Since the frag was new.
Let me know what you guys think!
