This clicking sound is annoying me

if the shells dont look like they have any damage (big holes) then i doubt its a mantis. when do you generally hear the clicks? night or day? the vast majority of mantids are diurnal which means you should hear from them more often during the day than the night.

so what clicks? well mantids obviously, but also, clownfish (and a few other fish), pistols, snails (youve heard that one), and visitherm stealth heaters.

If you included hermits in your cleanup crew, they're probably responsible for exterminating your snails. They could be clinking shells against the glass, too.

wI've had a trap in there for about 3 days not, leaned against a rock in case it's a crab. The snail shells have no visible damage.

I really notice the clicking when the lights are on. I do have a stealth heater, and I have 2 cinamon clowns.
