A fish that is normally the staple of some of the tiniest fish tanks on the market is now big enough to weigh down an ordinary fishing pole.

Monster goldfish have taken over Keller Lake in Minnesota. As an invasive species in the lake, these monster goldfish are wreaking absolute havoc on the local ecosystems. For whatever reason, people have decided to release their pet fish in the lake.

Minnesota Lake Filled with Invasive Species

The local City of Burnsville, Minnesota Facebook page posted about the invasive species in the water. There were initially 10 goldfish found in Keller Lake, but the number has increased to 18 more this week. There were some that even weighed four pounds and were 18 inches long.

While the goldfish at this football-size are intriguing, they’re incredibly dangerous and irresponsible.

“Please don’t release your pet goldfish into ponds and lakes. They grow bigger than you think! We recently partnered with the City of Apple Valley, MN and Carp Solutions to conduct a fish survey on Keller Lake to assess populations of invasive goldfish and other fish in the lake. Large groups of goldfish have been observed in recent years on the lake. At high populations, goldfish can contribute to poor water quality by mucking up the bottom sediments and uprooting plants,” the post states.

For those somehow incapable of continuing to care for a pet fish, there are several other safer and more environmentally friendly options.

The post urges people to instead give the fish to family or friends to take care of. Some pet stores will also take fish that people no longer want to care for.

CBS Minnesota reports that the city of Chaska is also having this problem. The city now has a three-year plan to manage invasive species so they don’t end up in the Minnesota River.

Massive Goldfish Problem

According to National Geographic, goldfish will usually be around 7 to 16.1 inches long and they weigh about 0.2 to 0.6 pounds. However, many fish will grow in accordance with their surroundings. This means that goldfish released into the wild can reach up to five pounds.

In November 2020, a goldfish that weighed about 9 pounds was found in a lake in South Carolina. The Greenville County Parks, Recreation, & Tourism posted a photo of the massive fish on social media. The post said, “Anyone missing their goldfish? This 9lb goldfish was found in Oak Grove Lake during some recent testing at our lakes. The work included electrofishing, a method of measuring the health of the fish population.”

Although it is massive, it’s still not the biggest. The Guinness World Record for the world’s longest goldfish goes to Joris Gijsbers. His fish was 18.7 inches when it was confirmed in 2003 in The Netherlands.
