Anyone got crabs?

[kien]

I've had quite a few crabs. I've removed most of the fuzzy ones with the hairy legs tho. I've actually seen those ones graze on SPS flesh. I have also had a bunch of the maroon ones with the flat pinchers. I removed a few of them but still have a couple in the tank. I don't think they do too much harm as I've only ever seen them pinch and graze on algae. They are built just like emerald crabs actually. Sadly no pictures they only come on at night.
