gotta read that thread. I guess I got the pests little hide-out rock in my order. I got 2 pistols(one I saw, and another I can only assume is a pistol), but I got 40 lbs of rock, and so far have gotten 2 stone crabs(one about the size of a quarter, the other the size of a pencil eraser), and maybe 30 gorillas. The one sneakiest gorilla I cannot get is the one I am most worried about. He is about the size of a 50-cent piece. HUGE mother, and if I come within 10 ft of the tank he darts into wherever he came out of. He is fast too. Every so many days I set up a trap, and catch a bunch of my hermits, 2-3 snails, and usually 2 gorillas. It just never ends. Even with all the pest hitch-hikers, I would not trade this rock in for the world. SOOOOOO much awesome life.
