LFS's suggestion for schooling fish

[luntiz]

So I went into a [acronym:aa11eb76c2="Local Fish Store"]LFS[/acronym:aa11eb76c2] and asked around about schooling fishs, I pointed to the 3 Blue-Green Chromis he had and he said, "[acronym:aa11eb76c2="Normal Output Fluorescents"]NO[/acronym:aa11eb76c2]!" A minute later he suggested having 5 Blue Tangs if I wanted a school. I mention that my tank is only 50 gallons and not even 50 gallons long. He said "should be okay." I wonder how many Blue Tangs he sold using that logic.
