Must See Video: Huge goldfish illustrates downside of dumping

Wildlife officials show of what can happen to common pets in an open environment

BURNSVILLE, Minn. (CBS News/KYMA, KECY) - Officials with the city of Burnsville, Minnesota are pleading with residents to stop dumping their goldfish in the lakes after they said they found football-sized goldfish.

City officials said they found 10 earlier this month while doing a water quality survey in Keller Lake. They say they found 18 more Monday.

Burnsville took their plea to Twitter posting photos of the giant fish and writing: “Please don’t release your pet goldfish into ponds and lakes! They grow bigger than you think and contribute to poor water quality by mucking up the bottom sediments and uprooting plants. Groups of these large goldfish were recently found in Keller Lake.

No word on how long it took the goldfish to grow that large.
