One wouldn't think such a small invertebrate would have individuality, but they sure seem to! My first emerald ate spas within seconds of being introduced, and nibbled my torch hours later. The second was in there two weeks before I caught him eating coral. Others have reported weeks, even months of good behavior.
I love the look of crabs, I just don't trust them. And once they develop a taste for corals, I've not yet heard of them losing the taste for them.

Someone stop me! Please! But... not just yet...

I have 1 in my 29g reef. Hasn't touched anything yet, also have 2 of them in my 90g reef, no problems there yet either.

Thanks for all the advice. I think that, as usual it depends on the individual crabs. I have two, one green and one that is a reddish color, pretty cool. I have been monitoring it and I think it is just hanging out underneath the candy cane. I figure if I supply a steady feeding regimen then that should be OK.
However , I do think that my Tiger Pistol killed both of my peppermint shrimp. I always hear him clicking. He did pair up with my Blue Spotted Watchman though.
The lesser of two evils is still an evil.

That would be my guess also. Most of them wont bother corals but there are exceptions esp. With crabs.



You can view many of my fish and corals in my photo albums in my profile.
