disappearing fish

Do you remember where your live rock and live sand came from? Might help narrow down what kind of crabs you have. In the meantime, take a look here:

No I don't remember were I got the rocks from or the sand. I was able to ID the red crab it's the red ridged clinging crab. The black crabs are really big. A little bigger then a quarter.

 

Well, without a positive i.d. on the black crab, it's hard to say whether or not it's a fish eater. Either way, I'd get those crabs out of the tank ASAP.

 

the same thing happened to me a few weeks ago. i lost a blue damsel one night, and then the other one the very next night with no trace of either of them. i have a sally lightfoot crab that i think ate them. my lfs owner said that he didn't think that is what happened, but the crab jumps at the fish and tries to grab them every time they go by.

 

Sally lightfoot crabs become evil when they get big and have been known to grab and eat fish.

 

They started to nip at my plate. Those little :-X

 

A-crab-hunting you should go

 

yes, I'm going spearing today

 

I had a similar death of a Coral Beauty angel, all that was left the next morning was one fin and some gunk that might have been a head. I am inclined to think she died of natural causes, but the body was eaten by my Banded Coral Shrimp, with help from two hermit crabs and the other fish in the tank.
