..sounds like out of a horror movie. My LR has been cycled for 6 months and my 90 gallon tank is also inhabited by two cleaner shrimp, five feather dusters, a yellow tang, a royal gramma, two 1" flat greenish crabs (emerald?), a few hermits, a flame angel and, just a few days old, a zoo polyp and a leather coral, my first foray into 'softies'.
Yesterday night, on the surface of one of my pieces of LR was a crab of sorts, about the size of a hermit but with a bluish gray somewhat hairy shell and brown curved fangs coming out of the bottom. It 'breathed' and every time it exhaled it would blow smoke into the aquarium, sometimes in with smoke rings just to make a point. The smoke would dissipate but it looked ominous.
I have reason to believe this is a rock crab (from another discussion board) and that it's not good for my tank in general (and less good for my reef).
Does anyone know about these, is it likely that it's what I have and what should I do about it? FYI, he/it is nowhere to be found today, back into the crevice he came from.
