Pests on Frags?

[jy808]

So I've purchased some new frags that's been in the tank for well over a month. I performed a dip to ensure all pests are out. I started to notice these small circle white bits on the bottom of the plug and wondering if it's anything to be concerned about?

I took the whole frag out and used a knife to scrape them off a little, then put them back in the tank. Now my torch isn't really opening up and not sure if I'm noticing the same white bits on the torch base.

Are you sure they're not spirorbid worms?

Looks like spirorbid worms, Harmless little filter feeders and a cool little addition to your biodiversity. Some people find them annoying because they can grow on the glass, They don't irritate corals as far as I know but they will grow on their skeletons.
