Looking for crab info

[DrChaos619]

Anyone have any info on Hemigrapsus sanguineus, the japanese shore crab?

I caught a bunch of them down at the beach today and they are hiding in my QT tank right now. I was just wondering if they are at least decent as reef janitors.

any info will help!

What I see of any shore or near shore crabs, they tend to be very destructive and tough, the habitat they live in requires them to be so. As such, I think they would find a reef aquarium to be very easy pickings. I would not chance it.
