Friend or foe?

[sarahbeth23]

I’ve had two small mushrooms disappear, my LFS tested my water and parameters were in check but as I was doing a water change the other day I pulled an old/dead piece of my hammer head that had broken off of a large colony out of the tank to do alittle closer inspection. The picture is very blurry because of how tiny these 3 little guys are but they were definitely moving. They are the little dark brownish specs on the white putty epoxy. Any ideas what they are? What should I do before the rest of my hard work is destroyed?

Looks like Chiton snails, which are harmless and algae eaters good cuc.

unfortunately I have those in the tank too and they’re more visible. I was able to get alittle better picture after trying Seachem reef dip which did absolutely nothing

Odd question, but do they have legs, or do they have a foot like a snail?
