I went to my first auction the other day, was hosted by a local tropical fish society and the guy doing the auctioneering owns an aquatics shop so I figured it'd be decent.
I was surprised though, cos we couldn't see the fish before bidding due to them getting stressed by being picked up and put down again, and they were being stored in bags inside boxes. But when the bidding started the guy just picked up the bag of fish, waved them over his head then when they were sold they were just carried across the room to sit with their new owner.
When I buy fish from a LFS
they put them in a carrier bag so they're not stressed by the changing surroundings, why wouldn't the same apply in an auction?
