If the bugs are super tiny, they're probably copepods. They'll almost look like a dot in size and are almost impossible to see on rocks
If they have a dozen legs, they are probably isopods. These I've had everywhere - rock, sand, glass. My fish have all but decimated them
Both are great fish snacks
The bigger ones you may see will look like small shrimp and are amphipods. These you'll see crawling around the rocks at night and you'll get molts floating around the water. Some fish will eat these too

The bryopsis I had was easy to pick off and my CUC kept it in check. I also run GFO and feed very lightly
Now that I have fish in the tank, I don't have anymore of it
I have an urchin, hermits, 4 kinds of snails, and 3 kinds of fish that graze on algae, although I don't know if anyone is eating it, or if it was just part of the cycle
