Do Kuhli's make clicking sounds like Clowns

[DanMan092]

Because if they dont then my aquarium may be cracking

It could also be substrate hitting the tank, as they tend to stir it up in the corners
(If you ever owned kuhlis, you'd know the whole swim to the surface, turn around and crash into the ground routine)

I've heard they do but never heard mine do it.

Mine don't click....

I found out that the "clicking" and other cracking noises was just the home made light holder. I have a 20 high light on a 30 long.
