2 fish, hold the tartar

I stopped in a parking lot yesterday and saw two dead medium-sized goldfish. OK. Now there wasn't a pet store anywhere near. There wasn't any reason for them to be there. I could theorize only three possibilities.

1.) They were living display fish at a restaurant; now dead
2.) They were from someone's house; abandoned and dead
3.) Ill-chosen sushi completely unprepped

They could have fallen from the sky, but that's as likely as being pulled from a location to be in the sky. However possible, totally improbable.
