I have an annoying little brown crab (loonie size, thats bigger then a quarter for my american friends :spin3
sitting in my birds nest coral, and the place that its sitting in the coral is loosing color and becoming brown. Tries to get rid of him plenty of times by pulling him out no luck. Probably do more damage to the coral then him. Tried to dip it in iodine he just sits there undisturbed.
Anything i can do to get him out of the coral? he sometimes wonders off but then comes back can't catch him, too many live rock.
