I was wondering what crabs and snails are considered reef-safe?
Well, I don't really have a reef, but I do have live rock, and eventually I may get some easy to keep coral.
I was going to buy some Queen conch crabs, but the LFS
guy said they sift though the sand, and I currently have a 4-6" DSB
and I have heard conflicting advice.
One group says to keep sand-sifting stuff out of there so the anaerobic area is left alone. The other group says the sand needs to be sifted around so it doesn't harden. Any thoughts?
Also, some live rock I got has a crab inside of it, and the LFS
guy said it was likely a "rock crab" and to get rid of it because it will just cause trouble. Any thoughts on this as well?
