This live rock came with some red turf algae, it wasn't spreading fast but it wasn't dieing off either, I was at the lfs today and saw a little pincushion urchin but I wasn't sure if it would eat this, turf algae
I put him in about 2 hours ago and he's got all the algae on this rock cleared off with absolute precision on the left side, im glad because it was impossible to manually remove, and I've had it for a few months.
