I ❤ Goldfish

Lake Tahoe, one of the deepest lakes in America has recently become infested with large goldfish. This problem became known during a yearly study of the lake in 2006. Many scientists are seriously concerned on account of these goldfish impacting other native wildlife in the lake.  "Goldfish are very good at getting what they need. They can potentially compete with native fish for food, vegetation and bugs". Additionally goldfish consume a lot of food in a very little amount of time. This presents another factor of their excrement which will ultimately pollute the water. Multiple attempts have been taken to stop them, like electrocuting the water. This has proved futile against the majestic fish.
