If the fish is at least swimming in the tank for at least 1 - 2 days and died another day, I would blame my friend for his tank parameters. But the fish arrive in such serious injury, obviously seller is trying to get rid of it not to mention that he did it with a plot, but it is really not right not to show buyers the injury and just bag it and ask buyer to leave. I believe reefers here are here for good deals and not fraud deals.
