Indiana wildlife officials have a message for those thinking about getting rid of unwanted goldfish by dumping them into a lake, pond or stream: Don't do it.
The Indiana Division of Fish and Wildlife warns that the small aquarium dwellers can grow "huge" in the wild, tend to breed prolifically and become and invasive pest.
That threatens native fish species, throws the food chain out of whack and decreases biodiversity.
Wildlife officials note that goldfish can legally be used for fishing bait in Indiana.
But there are other options, too. Officials suggest trading them away or donating them to pet stores, school museums or zoos. You can also ask a veterinarian or pet store for advice.
