i would breed then as u will be stuck with mostly ugly hybrids and shops wont take them off you and if they do they will sale them as what the look closest to
to be bonest if hes short on tanks he prob doesnt want to be raisin 50+ hybrids and not even noing the outcome of them if ther butt ugly no store will take them but they could be nice but more than likey ugly and drao in dull colours so i would pass but its all up to you
