More hitchhikers - Crabs aren't that bad...

[Jack]

I've had a few crabs and to be honest I'd rather not have them in my reef.

I think a lot of reefkeepers play the guessing game when it comes to these crabs, especially ones in our acro's. I've seen some crabs eat pollyps and tissue and others that were completley harmless. I just take any crabs I find in my tank out when I see them. I don't think they add much in the way of biodiversity anyways.

But, I do like porcellain crabs.
