No complaint here. I love this rock and this section of the tank. But there are these branch like tufts growing on it that sway in the current. Any idea what they are. They don't look anything like any type of plant or macro or hydroids ive seen. Ideas?

They look like Bryozoans IMO.

Yes, bryozoan.
