According to experts, thousands of goldfish have invaded Colorado Lake. The authorities believe that someone went to Colorado Lake and dumped a few gold fish in the water few years back and now they have multiplied into thousands.

Presently, the Colorado Parks and Wildlife rangers are putting efforts to understand what to do with the said fish population. According to experts, it was really shocking to see the fast growth in goldfish population. The problem has been recognized by Jennifer Churchill, a spokeswoman for Colorado Parks and Wildlife (CPW).

According to Churchill, it's really a serious problem out there. There are minimum 4,000 gold fish in the Colorado Lake and they can do real damage.

"These things wind end up downstream, they can introduce disease to the environment. They can outcompete our native fish", said Churchill.

According to the wildlife rangers, one option is that they are thinking is to drain the lake and start over again. Presently, the Colorado Parks and Wildlife is working with Boulder County advice residents to be careful if they want to get rid of their pets.

Ecosystem of the lake has been devastated as the population of goldfish has exploded. The district wildlife manager in Boulder, Kristin Cannon said this fish is not native to lake so they are very harmful to the local aquatic ecosystem.

As per the experts, the goldfish aren't contained to a fishbowl, goldfish can grow to be numerous inches long. Churchill said that adding fish to bodies of freshwater is not motivated and it is not good for environment and is illegal also. Churchill also said that among the local fish threatened by the goldfish are blue gill fish, sun fish, and channel catfish.
