UNIDENTIFIED SOUND

ScubaShane · Jan 29, 2017

Guys........did you ever hear the sound of a pistol shrip before? Or when you go swimming or diving and you smack two rocks together. Thats what im hearing in my tank. Its not a pistol shrimp, could be, but i dont see any evidence like sand tracks and most come out when you feed. I might have young Mantis that hitch hiked. They are good at hiding. Its not my hermits or snails smacking on the glass either. My tank is not creeking or cracking, although i thaught it at first and was nervous but ruled it out. Its in the same location and its consitant day and night. Anyone know of anything else that makes that snapping sound?

Have you lost any small livestock lately? Any trenches laying around that something could be digging?

No. I only have about a 1/2 of sand on the display side just for aesthetics. The back is bare bottom. I look under the tank every other night with a flashlight. No fish missing yet. I have a baby maroon so hed probly be the first to go. I had a pistol shrip snatch and eat a firefish before. I gave him away.

I've been having this too!!! Only at night though and it's not that consistent. So I'm definitely following this

Pistol shrimp is one snap for a time
Mantis is a series of 3 min

About how long after the lights go off for before the sounds starts?

After the lights go out when the fish start to hide as if he is snapping at them for being in his territory. And when the lights go on.

It sounds like it coms from the same spot. I can only narrow it down to the left side of the tank at the bottom half. Cant pinpoit sound. I search that area as best i can with a low blue light flashlight but cant find him.

Any baiting ideas?

Pistol shrimp sound like a coin tapping on glass. You'd see mounds of sand next to your rocks though. Even a small one can move quite a bit in a night.

You sure it isn't just your hermit crabs' shells tapping on the glass as they move around? How loud is it?

The live rock has been wet for over 10 years. I only started hearing it in the last month. Ive gotten some fraggs this past month but they were dipped. So if he came in on the fraggs hes tiny and survived the dipps. But its snap can be heard pretty well for somthing so tiny. ?????????????????????????????

Ive steked it out for an hour. Not crab or snail shells. There is no sand in that area just bare bottom. I can see the bottom of the rock under the tank. Always see copes and amphs. Acational bristle worm.

I float the frag bags for 30min to get to back up to temp. The i add tank water to bag for another 30min to raise PH back up. Then i dip using 4 to 1 ratio peroxide dip then iodine dip. Then i place the coral at the bottom and inspect it. When it opens up i move it to the recommended loction. IE mushrooms at the bottom. So if it did hike the recent frags it survived the dips and it was hiding verry well.
