I’m in the middle of a tank move and I knew I had this specific crab for a while now, but never caught it. Well l moved one of my rocks today in a bucket and I guess it was hiding there tonight. So: is it a bad crab or good crab?

Thanks for any info everyone!

I’ll let someone who can confirm chime in, but I think it’s a stone crab. I have one that came in on TBS live rock, and looks very much the same.

Looks like a stone crab or or some type of Xanthid crab which all are bad for your tank, not reef or fish safe usually and grow quickly, so send it to the sump! (just make sure there are no wires for it to claw on)

Thanks guys! I’m glad i got it out. Its probably the reason why I’m missing a couple of small fishes

Spineback hairy crab? But I say that about every purple xanthid
