Something eating my acro

[bellasdad0911]

Have had a blue acro eaten on some of the tips and maybe even half way down. It’s not a flat worm or red big issue. Coral is healthy and colorful. I decided to dip the entire rock that it’s on in revive. This is what came off.

Collinista snails and Amphipods I believe. There may be more but you need a different back round in the image to make out certain items.
