I agree with Steve on the tangs, they need a lot of swimming room and can become agressive towards other tangs when they get bigger especially if space is limited.

I believe I read on wetwebmedia that specimens larger than 3-4" adjust fairly well to aquariums and are pretty hardy. For some reason I remember the article stating something like specimens of less than 4 inches only have a 25% chance of acclimating to an aquarium.
