Hitchhiking crab ID

It has a reddish brown color. Caught him on my stag coral that’s been mysteriously losing tissue.

Looks rather like a red Mithrax crab. Related to emerald crabs.

They often eat algae, but ... they're crabs, and most crabs will eat anything.

Maybe he's your new sump-lord?

I put him in the sump but now I feel bad. Maybe he was just cleaning algae off the coral skeleton.

I thought Mithrax but those pincer tips look to pointed for a mithrax.

When it doubt take it out.

Looks like a Chlorodiella cytherea. Genus in the Xanthidae family. Don’t feel bad about taking it out. Here’s an article for you so you can confirm:

I thought Chlorodiella had wide claw tips a bit like Mithrax. I don't agree with chucks addiction write up on Xanthidae, some you could risk and some I would happily add. But the truth is you can not trust any true crab.
