Biology a question

[Dez]

I didn't dismantle my tank until I saw the critter. I had clicking noises come from the tank... I was in denial, I thought it was a pistol shrimp because no fish were missing...maybe a chromis or two...my hermit crabs and snails slowly dissappeared ( I thought that was normal...).. My sallylightfoot crab dissappeared, couldn't figure it out. Well, I lived like that for about 6 months, then I finally saw the bugger...a mantis shrimp.

I took an afternoon and removed every piece of rock and still didn't find it... then I squirted hot water in the rocks with holes and heard a sound in one of the holes..

Cracked the rock open and found it..
