SRC Member james72 Posted June 29, 2014 SRC Member Share Posted June 29, 2014 I always take out all the crabs from sps cos I do not know how to differentiate between the good n bad acro crabs. But I feel that good acro crabs are there for a good cause which can help in pest controls. Can anyone share some knowledge and pics of friendly acro crabs and the nasty crabs for sps?

Ken_ng Posted June 30, 2014 Share Posted June 30, 2014 Hairy crabs are not reef safe. I've got a strawberry crab in my tank. So far it has not touched the corals yet so should be okay I suppose. Quote Link to comment Share on other sites More sharing options...

I have a a. Valida that slowly stn from the mid way and I cant figure out why... till I realise that one tiny hairy crab is having a good time eating the SPS. Once removed, the Valida recovered within a week and thrive Quote Treat others the way you wanna be treated... Link to comment Share on other sites More sharing options...
tofubox Posted July 1, 2014 Share Posted July 1, 2014 I've link this before to a fellow reefer to help id crabs. I use this website all the time for id-ing crabs. As mentioned almost all the hairy crabs are not reef safe. But don't be fooled by the smooth shell ones too. There are a few not reef safe, best to always id them if unsure. http://www.chucksaddiction.com/hitchcrabs.html Cheers Quote I Love Stagsss Link to comment Share on other sites More sharing options...
moonwater Posted July 1, 2014 Share Posted July 1, 2014 Thanks for the links... i've got 1 hairy crab that is about the size of my thumb, but i only notice it chopping on coralline algae?? almost caught it with a pincer a couple of times... would it be advisable to catch it with bare hands??

honkit Posted July 2, 2014 Share Posted July 2, 2014 Unless they are commensal crabs for SPS corals, I would personally avoid putting any other crabs in a SPS dominated tank due to crabs' unpredictable and predatory behaviour and feeding habits.
