This clicking sound is annoying me

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.
