I somehow missed the part about it being in a classroom. For an eye-catching tank, I'd personally lean towards a smaller mbuna or male peacock mix or both.
I truly love my Tang tanks, but unlike my Malawi tanks, they're best enjoyed sitting still and staring at them for long periods of time... more subtle behavior, I guess. In a classroom with lots of movement and not much time for kids to zone-out in front of the tank, Malawi stuff may be more kid-friendly. How old are the students?
If I was to stock that tank with Tangs, I'd go with:
-group of gold occelatus (maybe 4-6 to start out)
-pair of Altolamps calvus or comps
-pair of either cylindricus, leleupi or Julidochromis
-4-6 Cyp micro or leptosoma Utinta (1M/3+F)
Build at least two piles of rocks, separated by sand for the two pairs of rock dwellers with shells in the foreground.
I wouldn't put any feather fins in a tank smaller than 75 gallons. They're vicious.
