Next in the saga of “what is taking over this tank”... Could someone ID these little brown things? They’re on the rocks and the glass.

Red Planaria Flatworms. Remove them by siphoning them out with a hose, or you can add a wrasse to your system to eat them (assuming your system allows for it) Or you can try flatworm exit, however I have no experience with that product.
