Algae of some sort, a tang will clean it up.

Hydroids. Common in newer tanks. They’ll eventually clear up.

All my snails are in my dt guess I’ll guy buy a small one or two and throw it in the little fuge. I’m guessing hermits don’t eat them?

So my understanding of these is that they are filter feeders. By lowering the amount of food available to them they eventually starve. I cleared mine by gluing frags on top and target feeding the fish so there were very few leftovers for them to eat. I do not think they are harmful though, had em for a while and haven’t seen them in about 4 months now after that so they never really caused a problem for me
