Cool! Just got back from my LFS and they actually have a Citron Goby. Didn't get to see him though, he is in a huge tank with a bunch or corals and other stuff, so I couldn't find him.
So far, I think I will end up going for the Citron, a firefish, and a neon goby.
They had a sweet little 6 line wrasse, he was less than 1 inch, but I'm afraid I would be stretching it to put him in my tank. Any idea how quick he would grow?
