I can tell you that neons will school but they also tend to have rogue groups. I've got a nice mixture of neons and cardinals and they'll school together they don't seem to see the difference between the two species
I have 7 Rasboras and i must say , they are a Tight schooling group as well. all day long from one end of the tank to the other..back and forth like a tennis match.
May have one straggle along in the back of the group every now and again, but he usually catches up on their way back across the tank
