What will eat all this junk?

[shartpants007]

Are there any small snails or hermit crabs that will eat this stuff off my rocks? I used to be slightly more well versed in algae identification and elimination, but my tank has been pretty healthy for a while so I haven't had to deal with it. Now though, I have this stuff all over my rocks and I'm hoping there's a small creature that will get rid of it for me.

Realistically the answer is no. Is usually a symptom of a water parameter imbalance or, if a new tank, just a normal part of the cycle.

Pin cushion urchin may but in reality, best is to remove rock and scrub with toothbrush and peroxide in bucket of tank water
