I had a school of 5 in my community tank and they did fine in my opinion. They did a little chasing here and there but only amongst themselves and it was nothing aggressive. They were housed with guppies, endlers, and ottos and they were not aggressive to any of them.
I will say though that they mysteriously started dying off one by one and only have 2 left, and they show a lot of aggression now that they cannot school.
6 or more IMO would work or if they were with similar sized tetras I would think.
