On a big river with plenty of room, such as the Thames, how does the behaviour and habitat of choice of say, a 2lb roach, differ from a 1lb roach?
Will the larger roach stay in tiny shoals of what's left of the bigger roach? Or will they stay with the larger shoals of smaller roach...or will they shoal up with bream?
