Goldfish have found their way into Lake Tahoe, and that's a big problem for some native species in the lake. Researchers in the area have found some goldfish weighing as much as 4 pounds, and those fish are responsible for eating minnows that native species rely on. Why are goldfish in Tahoe so bad? And how do you get them out of the lake? We talk with a researcher who has studied goldfish in Lake Tahoe and why they're such a nuisance.
