Tonight I added a little guy that we got in at the LFS where I work, a Rainfords Goby. These guys have always been one of my favorite fish, great personalities and color. I saw him in the shipment, and looked at the price ($16 plus 20% discount) and decided to bring him home.
He's fully acclimated, and just now I saw him come out from hiding.

So far he's getting along swimmingly with my clowns.
I have to admit that he wasn't on my stocking list for my tank, but I couldn't resist. He'll take up very little room, and have a minor impact on my bioload.
