Please help ID crab!

[WhiteTang]

Hello fellow reefers!
Its been some time now that I found this crab in my tank. I am not sure if it is a pest or not. It doesnt seem to bother any corals or shrimps (sexy shrimp) I have in the tank and is happy to get out and be seen (sometimes).
I tried searching to ID it without any luck. Does anyone recognise what kind of crab this is? You can see a very clear video I took HERE. Just skip to 1:12 for a close-up.
Thanks in advance

No idea what he is but he looks bada$$. Looks like pointy claws so little chance of being reef safe.

I have no idea what kind it is, but it is one cool looking crab! Even if it turns out to be a troublemaker, I would find a place for it - be it sump/fuge/whatever.

Awesome crab. No idea what it is but, if it's reef safe, I want one.

That is a really awesome looking crab! Your shrimp sure doesn't seem to fear him! I'd leave him since he's not hurting anything, although it did look like pointy claws and that seems to typically point towards not reef safe.

I've never seen that kinda crab before, but it sure looks cool. You might name it Spike.

He looks cool, but I would not trust him at all. Those pointy little claws are perfect for ripping up corals.

I had one of those once, take it out they get really huge really fast

ruby red mithrax crab. Same temper mentality as an emerald harmless when they are small.

Hmm you seem to be right. Cause it has doubled in size from a month ago I saw it. Did yours bother your corals, shrimps or anything in general?

You must be looking at something else because that crab looks nothing like a mithrax crab. He is cool looking but I wouldn't trust him in my display....I wouldn't kill him, I'd sump him.

So, anyone know what this is with certainty?

Nope. Im really curious as to what it is. Anyway I will keep an eye on it. I wouldnt want my acan go missing. He can nip as much as he wants on the zoas though

Thats not true. Crabs are not bad. They are just like any other living thing. If you feed it it will be happy and leave everything alone.
I have a couple sexy shrimp and if i dont feed them one day they start nipping on zoas.
