Good cleanup crew! How did you acquire them?

Looks like you might have a po3 or po4 issue or maybe to many nutrients in the water column at least it looks that way by the color of the acro kinda on the brown side.

I have rock releasing phosphate to the tank.

When I upgraded my tank, I didn't do it right. I used BRS dry rock with tap water to start up. All rocks turn green but now slowly havr colorine algea cover it.

Can you get a closer pic of them? They look like banded trochus snails?

Nope! Harmless algae eaters. Totally nocturnal
