Found this lil hitchhiker tonight, anyone actually know what kind of crab it is?
And please don’t just say “how cute” or “I want one”

Thank you!

I would keep that bugger!! I don't know what it is. But MY goodness...

I will go with gall crab though.

Also, this is a male gall crab.

On the question of is it reef safe. Yes and no. They can burrow into corals which can kill corals. I don't know if the males burrow or not. I am sure they do. Most of the time, lps will die. Gall crabs use corals as a home for protection and eat pests around said coral. In our aquariums, it seems lps don't fair well with them. There was a thread of them killing elegance corals for example. Only one I can remember.
