So, last night (around this time) I added a Yasha Goby and Pistol pair, I had to do a bit of work to re-arrange the rocks just before I put them in, and had to move a rock or two on the top line (near the top of the tank), but it didn't really move anything on the sand bed.

I've seen the Pistol, but where on earth is the goby? Should I go searching for it? I've not got much in my tank (except for some snails, and some algae, a few frags and 2 other fish...)

So? Comments?
