Click Click Click Click!

[speedsport]

I have been hearing clicks from my reef tank latley. The tank is about 4-5 months old and most of the live rock is from my first tank. I have added live rock here and there form the LFS. The only new rock I have added latley was in my fuge. I havent noticed any missing crabs or any thing. I do have a pistol shrimp but the clicks are too quick to be him. This is a noise I have never heard before. Could it be a mantis? If so how do I find him and cach him?
Any help would be great.

Thanks

The pistol shrimp that I have heard pop a lot faster than the mantis I've heard. It's probably your pistol.

mantis strikes are usually spaced out further than pistol shrimp pops.
