Crab exo-skeleton found. Any ideas?

[Lyvric]

Hey guys, I found this hollow shell in the sand. It doesn't look like a crab, just a shell/shedding

Any idea which one this is, if it is still alive?

If he's a 'bad guy', how do I catch him?

I would say he is a bad guy because of the black tips on the claws. You need to do a little spying at night to figure out where he is then set up a trap for him.

Yes they are bad they will try to eat your coral or anemones.

I found the soft, freshly shed snail culprit. I don't have a sump/place to keep the cutie, so my husband offered to do the work.

Bye bye little villian.
