Watching a program about Florida's Everglades on one of the nature channels in which biologists are conducting a survey of fish found in the dry-season 'gator excavations, and time after time, finding non-native species. "All exotics in this trap," one of them exclaims, and the voice-over announcer goes on to explain, "These fish are the ancestors of fish from fish farms and home aquariums."
...This means the problem in FL is even worse than I thought; those sneaky piscine invaders are going back in time and sneaking into our hobbies and food production! Quick, release the Burmese pythons! --What?
