zebrafish shoals

[L R Hughes]

I am an undergraduate at Sheffield University and for my third year 
project I am studying the shoaling behaviour of fish using zebrafish.
Basically, I am trying to find information on shoaling 
sizes of zebrafish in the wild - do they ever form large 
aggregations?

I haven't had very much luck in finding this sort of information, and I 
would be very grateful for any help you could offer.

Thanks, in advance,
