From fresh KP live rock. The crab is tiny, wasn't sure if it was a xanthid or stone crab. I hear a popping that I thought was a pistol shrimp but maybe it's the crab? Whatever it is it must be very small. The thing I thought was a stomatella looks more like a zoanthid eating nudi.

Two more crabs each in their own hole, very well camouflaged. All the crabs seem like Xanthidae of some kind. The one on the left has white fuzzy claws and white fuzz

xanthid crabs, they should go to the sump so they don't do crab things in the display tank. the other is a polyclad flatworm, they can be quite untrustworthy, some even eat small crustaceans, corals or clams, not sure about your guy, maybe he is cool. do you live near jersey by any chance?

Thanks, I agree it's a polyclad worm. He went down the drain. The crabs are going to be a bit trickier.

No I'm in the Bay area, why? Did you want the crabs or something?

Nope it is nudibranch. Look like Dorid sp.
How do you tell the difference?
My apologies, I was wrong, yes it is a dorid nudibranch, the "eyes" position and the respiratory structure give it away. a polyclad has the "eyes" on his "nose" the dorid always has them behind his "nose"
