found crab: are his claws pointy or no?

[kirkland]

I found a similar guy last week. This time, I made sure to get better a better pic, especially of the claw. I have now found 3 of these guys in our tank. The first one didn't look as stripey or hairy, but exact same body shape and base color. Are they bad crabs for a reef? Claws look pointy to me but it never hurts to get more opinions!

looks like a mithrax crab, most are okay from what i hear, but I am not 100% so I would wait for more opinions

Yea i agree. Some call them emerald crabs. I have 3 of these in my reef. They eat bubble algae.
