The Goldfish is non-native to our park. The goldfish is a domesticated version of a less-colorful carp native to east Asia. It was first domesticated in China more than a thousand years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration and coloration. Introduction of goldfish into the wild can cause problems for native species. Goldfish can hybridize with certain other species of carp. Koi may also interbreed with the goldfish to produce a sterile hybrid fish.
Fun Fact Goldfish, like most fish, are opportunistic feeders and do not stop eating on their own accord. Overfeeding can be detrimental to their health, typically by blocking the intestines. This happens most often with selectively bred goldfish, which have a convoluted intestinal tract.
