Ahh yes also just tonight I picked up a paired goby and
pistol shrimp. I'm not sure what the type of pistol shrimp it was but it is a little smaller then my cleaner shrimp and it has red and white stripes. I am told the goby is a Amblyeleotris randalli aka Prawn goby. I think it looks awesome it has a white base coat with orange stripes. I took pictures before I put them in the tank. Once I put them in the tank the goby was instantly gone, but I was able to track the pistol shrimp for awhile. He went behind my liverock after a few min and I lost him.

I kept looking around to see them, but they never came out so a few min ago I moved the lr around until I found them under like my second largest chunk (of course they'd be there) So I put the rock back and I hope they start digging pretty soon.
P.S. Sorry about the quailty of the pictures. I am a poor college student and only have an old hand-me-down camera. If I ever stop pouring all my money into my tank I might buy a new one. Heh
