I suspect they won't really care a lot if there are many or few. In
the wild, they don't school very much.

Goldfish in the wild? Or wild carp in general? :-)

I know my wakins school, the 4 of them are always in pretty close proximity
to each other.... now the fantails, they go off and do their own thing.
Probably because they know they can't keep up, so why try? ~ jan
