Killer Emerald Crab?

[litebulb]

So in my biocube 29 I have/had a purple firefish until it went missing. I was digging around checking out the rocks and as I turn the large rock over there is the ******* crab with a hunk of meat in his claw. I'm also missing 2 hi fin gobies but I found one hiding under the pump lol. Is this normal for anew emerald crab to kill my favorite fish? I put his butt on time out and threw him in my new to me 210 tank that's been running for a couple weeks.

They can, but my guess is it died and the emerald got an easy meal. Do you quarantine?

what he said more than likely he was being opportunistic

They are crabs and if their primary food source isn't available, they'll eat just about anything they can get their claws on. I had one that ate 2 of my gobies and I've heard of them eating Zoas.:mad:

Man he was a healthy fish but I guess anything is possible. He loved hiding under the rock in holes and that crab snuck up on him I think. He would almost eat from my fingers (just was comfortable when I fed with being close, the fish of course)
