Snapped some photos on my phone of a few more removed from the zoa tank (Have been constantly hand picking the rocks). Ended up grabbing the big one while flipping a rock over so my hand is pretty ****ed off now.

These are survivors after the dip, 2 nights of staking the zoas out and using a home made trap.

I have those same ones.
Itchy burn too i must say, vinegar is supposed to help u can try it and see if it works for you. (i never noticed after trying)
I dont mind those guys, they clean the places my crabs cant go.

I have a lot of these worms and they never affected my zoanthids. But I did have problem of zoanthids shrinking to nothing and it was caused by Seachem phosphate remover aluminium based. The shrinking stopped when I removed that stuff although some polyp have yet to recover and they are still tiny bitty but they have stop the shrinking at least.

the one I had that was eating my zoo's wernt red at all, they didn't even look bristily untill you looked real close and its "legs" were bundles of fibers. to me it looked like a centepede from hell :mrgreen:
