Hi, I need some help IDing these little white critters. I have been stocking copepods off and on for a couple months so I initially thought they had grown and settled in the tank however these things don’t seem to move like copepods based off of the videos I’ve seen. They are stationary, hang onto the rock work, and I never really see any of them moving. Apologies in advance for the picture quality and the green hair algea. I’ve been in a three month battle with that.

They look like sponges to me, especially the ones with the rounder base. Growing in the shade is common for sponges. Assuming my ID is correct (it might be worth pulling one out to feel and examine it) then they're good guys. No need to intervene. They filter-feed.

Sponges are really fascinating and you got lucky growing a bunch of good guys 🙂
Some sponges can overgrow corals but pineapple sponges stay small and don't harm anything.
