I have no firsthand experience with rainbows either, but most of the ones I've read about get around 3-4 inches and are super active which means they need a pretty big tank (thinking 55 gallons here). They are pretty, though.
Hrm...most tetras are soft water fish, and get pretty big (2-3 inches) and in a school would over stock the tank most likely. Is there anyway you can test the gh/kh/ph of the school's tap, for exact numbers? It'll make it a bit easier to pin down exact fish for the tank :)
Eh, I have API but I don't use it often, and well, the teacher never has either.
There are rainbows that are only 1 inch as well :p
And I've always had smaller tetras, like neon for example. Sent from Petguide.com Free App
