i just set up a 5 gal s/w nano tank and i put 2 clown gobys and one fire srimp. i know its a small tank but i wanted a coral tank and this was the best i could do right now. but about the fire srimp who eles has one and how well do you like them. mine always stays on his rock but he is one of my neatest s/w fish i have. maybe it is because he is new but i still like him.
