Would this Hitch hiker be Reef safe? VIDEO ADDED

Yours is not an emerald crab. The claws look very short and sharp. I would flush that bad boy.

 

Rather than flush throw him in the sump, he'll do some good in there. I can't bring myself to flush stuff, even if its destroyed half my tank...

Don't flush!! So sad. I could never do that. Until you know for sure if he's good or bad put him in your sump.

 

if it ends up eating your corals/inverts/fish then it would be causing big problem, then trying to catch it because its killing your livestock and trying to catch it would PITA then you would want to flush in anger

 

Wow sorry so long on Reply i went out of town for a little bit. Yes he has Red eyes and red joints i will get another picture right now a up close one... give me a moment. I will not flush him if anything the LFS Will own this little critter.

 

Doesn't look like an emerald to me. I would throw him in the sump, but I like crabs.
