I too have the knocks, I have had it since the beginning, so I think I got a mantis from the LR, never seen it, nor have I ever seen any piles of sand. So I am thinking it lives on the backside of my rockwork.
The Frog's Croak really baffles me, I don't shrimp croak!

I suppose frog's croak was the wrong way to describe it. I mean that it sounds like more than just two hard surfaces tapping together, there's a resonance to it that gives it an extra "something". It might just be the echo the sound makes bouncing around the inside of the tank.
At first I was terrified that it was something banging on the glass of the aquarium and that it might break, but I couldn't reproduce the sound by knocking against the glass with anything (I probably looked like an idiot trying to do it too).
I suppose I shouldn't worry about it unless things start disappearing.
