Goldfishes are cute alright? But Lake Tahoe caretakers don’t think so. While for us, goldfishes make cute pets in our aquariums at home – they are proving to be a big threat for the Lake Tahoe’s ecosystem. Recently, a giant goldfish, nearly 1.5 feet long and 4.2 pounds in weight was found in Lake Tahoe waters.

Lake Tahoe is a large freshwater lake in the mountain range of Sierra Nevada of the United States. Aquarium owners in the nearby areas probably dump the goldfishes there. These goldfishes, not only  feed on the native species of the lake, they also excrete nutrients that cause algae depositions, which are threat to Tahoe’s clear waters.

As a result of this goldfish invasion, the native species are at big risk.
