lol ! You’re right though .I assume if the truck fell off a mountain road, maybe.
If the fish came out of the bag like that, then it’s seems fair that the seller would cover that and chargeback the transport for damages.
Now if the fish actually was in your system, only for a few minutes, possible damage done by others.
Most good retailers will provide a “arrive alive” guarantee and while not dead on delivery, certainly has trauma.
Fish came in like this and went straight to a quarantine tank by itself.
