Fish at the swap is a difficult proposition. It's cold outside and dragging fish around in unheated bags, with no oxygen source no less, is going to be difficult/dangerous at best.
The Vendors that will be selling fish there will hold them in their heated/oxygenated tanks for members until the members are ready to depart for the day.
In order to keep this thread open, you will have to post prices for the fish so people know their value as we don't allow 'best offer' threads, even though you also mention trading. Thanks.
