I've come to a "casual observation" that schooling fish will school if the size of the school meets some fishy minded criteria..
If below that threshold they are content w/ being loaners..there is no safety in say 4 in number but there is in 10...

Of course people also come up w/ some odd things ..like I was once told you can't have even #'s for some schooling fish..
like 9 was ok but not 8...
didn't know fish could count..

Second criteria is "open-ness" of the environment..If overgrown no need to school much..
