What's the craziest thing you've seen come out of your live rock?

I was looking at my zoanthid in my tank last night and I notice something behind him. I thought it was a hermit crab's legs, and then I looked closer and I saw a claw. It's a crab! I didn't buy it so it must have been hiding in the live rock the whole time. He looks identical to my emerald crab just deep purple.

I tried looking him up and I read a few articles on crabs doing damage to SPS. I don't currently have any SPS in my tank. This crab's claws look identical to my emerald crab's claws. Do I need to worry about this crab? Could he be safe like my emerald? Could he be the same species as my emerald crab? I just caught myself saying "he" the whole time. We named him Shadow already. If I see him again I'll try to get a picture.

Nudibranch, worms, amphipods, copepods, a huge crab (I gave it back to the initial LR owner)... Dinoflagellates too...

Purple coraline

Emrauld crabs are not reef safe, except if they have something to eat all the time. When they starve, they tend to eat corals.

Bicolor blenny was the coolest I've found, I have maybe a half dozen or more pistol shrimps that came in on this rock. They behave so far, but it sounds like a problem machine at times

Has anybody heard of a spoon worm? It hides inside a rock and you will only see it's arm or I would say its tongue that is shaped like a Y. It stretches like a rubber band at night and clean up the substrate. I called it the Marine Alien.
