Is this is red mithrax crab? Reef safe?

Thanks!
 
Yup good catch @ptrahan. He molted! Completely hollow inside, even the legs. The tips of the claws are black so definetely looks like a gorilla crab from my image search.

So now I have to hunt him down. Anyone have tips on how to to trap him? He must be living inside of my rocks somewhere and they are covered in corals, so I can't easily take them out.
 
And the crab hunt begins in earnest...

I can't see the image clearly enough, but it could also be a strawberry crab if it's bright red (they have white dots and black tips). We had one for a few years and he was a model citizen.
 
Feed him with shrimp until you gain his trust then run him through with a lance!! Haha. Or, you can make a trap out of a plastic bottle with the appropriate sized opening. Cut the top off and invert it as a funnel. Attach it to the bottle with small zip ties. Add bait and let it set overnight. May take several tries. You might also catch desirable critters.
 
Still haven't caught this guy. I have seen him again late at night, so he is around. He doesn't seem to be doing any damage... yet. But I know that I'll pay for it one day if I leave him in there.

I'll keep trying over xmas. Going to try to catch sight of him late at night and see if I can disable him with my high power laser that I use to kill aptasia. Sounds kind of cruel but I'm at a loss since other things aren't working.
 
I've torn a 92 gallon tank apart to get one out. We found out that's what was dragging the ricordea to the back of the tank and eating them...

...the trap is a great place to start. Or kill it. Best of luck!
 
Gorilla crab! Black tips n fuzzy I’ve used a long needle on a stick (like a old trash pickerupper) as a spear before and got one out they are masters at nabbing corals and eating them in their little hideyhole

Soda bottle traps scattered around the tank worked aswell for the smaller one but the big guy was too smart but didn’t outsmart the spear haha

To make the bottle trap cut off the top around mid bottle invert in back into itself and put meaty food inside they will climb in and not be able to get out
