clicking sound in tank

[christyf5]

Soo...if one had a pistol or mantis shrimp in their tank it would make a clicking noise right? Kind of like a tapping sound against the glass? Is it fast or slow? Anyone have any experiences with this?

Reason is, something is in my tank making that sort of sound. Most times it is a single click, then sometimes followed by another a few seconds later. The clicks are never super close together, I'd say they'd be about a half a second apart or longer and theres only ever one or two. It happens more when the lights are off (ie. the morning) but sometimes when the lights are on as well, and of course never when I'm standing in front of the tank looking for the damned thing. I thought maybe it was something knocking around in the current but I can't find anything.

Am I just paranoid? Wait, don't answer that

*sigh* I never seem to just be able to sit around and enjoy my tank these days. Its always something

Thats interesting... Sometimes when there is a little peice of sand that gets sucked up in a pump it makes a little noise when it hits the impellar. Just a thought though.

I hear the clicks too in my crab infested cube tank. My guess is that anything with claws can probably cause the occasional clicking sound.

Sometimes when a snail is near the edge of the tank the current blows it up against the tank wall, and its shell makes that clanking noise. I have a pistol shrimp and the sound is subtly different. Next time your hand is in the tank snap your fingers under water, that should be close to the sound a pistol makes.

My red pistol makes clicks exactly as you described. Most often one click, sometimes two, rarely three. And usually more often when the lights go out.

Pistols dig a lot, so you should notice large amounts of sand moving around if you have a pistol, otherwise I would suspect a mantis.
