Is this a reef safe crab?

[R33FERnatic]

Anyone know what kind of crab this is? I found last night in my tank. Should I put him in my refugium or display tank?
Please advise.

He only comes out at night after the lights are off.

Hard to tell. Where/on what did you find it on

If it's not a mithrax (debatable), porcelain or acro crab, I think it is a sump critter. That doesn't look like any of those to me (and not a decorator, which are supposed to be reef safe with caution). Also not a Sally.

When in doubt, kill it

Or. Or. Ask someone here if they have a sump in which they would like to entertain a very special murder crab.

I don’t know where it housed. I have a bare bottom tank and saw it came out at night. I decided to remove him just in case.

I feel the same way. Better safe then sorry.

I feel bad to killing him if he’s the good guy or someone can enjoy him.

i'd see if an lfs would like him, some people like weird inverts

I've managed to give away 2 gorilla crabs just by checking this forum. I would imagine that an interesting crab like that would go quickly.

Will do. Thank you!

It's a Red Egg Crab(Atergatis integerrimus), also known as a pancake crab!
They're omnivores, mostly feeding on algae, but they'll also eat worms, fish, and whatever else.
Not known if they eat coral but I'm guessing it's unlikely. They're also toxic(if eaten), they contain the same tetrodotoxin as pufferfish.

This is exactly the answer I was hoping to get. Thank you Pygo!
When you say they eat fish, do they catch and eat live fish. Or fish about to die and small enough for them to eat?

Can't confirm, there's not a ton of info available about them. But, they are generally pretty slow moving so I'd wager it'd be dying/dead fish mainly.
Up to you, but my vote is on reef safe with caution(for now). Not sure what you have in your tank that's valuable and at risk, but if it were me, I'd let him stay and observe him for a while
