3000 goldfish were found in a lake in Boulder, Colorado and this number is still growing at a high rate, which has totally baffled the scientists.
The invasion of this exotic breed of fish has bewildered the conservationists and they are rushing to this lake to have a look at this natural spectacle. This breed of goldfish are called as "Koi" and these are the fish who are gold, white and black in color and are generally found in artificial ponds and aquariums, according to Natural World News.
This huge school of goldfish was first spotted by a park ranger in Boulder's Teller Lake, Daily Mail reported. The officials who has carefully examined this place have said that only 4-5 goldfish were dumped in this lake about 2-3 years ago and since then, they have inbred and multiplied to so many.
These many goldfish are feared to destroy the ecosystem while attempting to eat resources and might potentially introduce a number of foreign diseases. The experts say that such a huge number of goldfish at a single place can prove to be devastating for the surrounding area and might also contaminate the water of the lake.
Another concern here is that in case this school moves downstream and fall in to the main water body, they will come face to face with direct competition with other fishes and this will totally disrupt the ecosystem.
Officials are planning to either drain the whole lake out, or kill some of the goldfish with the method of electroshocking, in which they will introduce an electric current in the water which will completely destroy the fish.
Officials have also warned the local residents of Colorado that it is not a good idea to capture any of these goldfish and take them home as a pet.
