That's what I'm thinking of calling my aquarium. First my pistol shrimp disappears for over a year before turning up (after 2 tank moves). So I decided he needed a goby friend. I bought one at the local fish store 2 weeks ago, haven't seen him since. Till last night! Now he just needs to find the shimp on the other side of the tank. I'll try to get a photo of him, but he's still pretty shy. Phil
