What's something that makes sound?

[SeaCucumberFan]

I'm looking for good inverts/fish/coral to put in my 25 gallon that is probably actually 30 gallon reef that makes sound. I've heard triggers make sound but my tank is nowhere near the minimum tank size. Are snapping shrimp reef safe? Will they eat fish? Will my CBS and emerald crabs bother them? I'm looking for something not too loud but still audible so it wont bother me when sleeping.
Livestock that may bother:
-CBS
-Emerald crabs (lots, possibly even breeding)
-Valentini
-Blue damsel (No, he is not a "satan")
-Camel shrimp

Livestock that I don't want to get eaten:
-Unidentified sea cucumber (theelothuria)
-Valentini puffer
-Donut coral
-Mushroom corals
-Green BTA
-Bee sponge
-Coral banded shrimp
-Pajama Cardinal

Any suggestions welcome

Pistol Shrimp are very cool and make occasional snapping sounds. Mine is mostly reef safe, but sometimes eats smaller snails and hermit crabs. And when one of my emerald crabs get too close, it starts snapping like crazy at the crab. It leaves larger snails, hermits and cleaner shrimp alone, though.

I'm not sure about the Coral Banded Shrimp, though. I hear those can get pretty aggressive and you might start having issues with that guy. And the puffer may eventually decide to sample the Pistol Shrimp.

I think you have an okay chance of success, though. Your stocking list is about full already, but if you're careful and keep up with the maintenance and/or have a good skimmer, I think you will enjoy keeping a Shrimp Goby paired with the Pistol. Very interesting behavior, with their symbiosis.

Ok thanks. I didn't buy the emerald crabs, they came as hitchhikers on LR.I'm mostly worried about the CBS, I have also heard they can be pretty aggressive :s . I have considered returning the CBS though, but I'm not sure how to catch it and my LFS will just replace it with a smaller one anyway. The CBS doesn't attack the much smaller camel shrimp but I don't think that means anything.

Clownfish grunt but a nice bellus pistol shrimp would be my choice, probably with a yellow watchman goby.

Mantis shrimp also make some noise as they hammer away on snails. They won't mess with your coral, but wouldn't work with the rest of your stocklist. I would also choose a pistol shrimp.

Tiger pistol. May kill small fish, however.

Thanks for helping guys! I will get a pistol shrimp. Will it eat my puffer? (About 2 in)

I'd be more worried about the puffer eating the pistol.

I'd be more worried about the puffer eating the pistol.

It hasn't ate the 1.5 in camel shrimp.

The pistol can protect himself
