I have read on this website that a fish is pez or pescado depending on whether it has been caught from the waters by human.
I understand that the usage of the words is not dependent on whether the fish is alive or dead but rather on the intention of taking it out of the water. So, if a fish is taken out of the water by a person for the pet fish industry, what does that make the fish (which will be kept alive and transferred into an aquarium)? Pez or pescado?
What if the fish is killed and subjected to a taxidermy treatment for exhibition purposes?
