White cloud minnows are native to China, but are a popular aquarium fish in Australia. Thought to be effective in controlling mosquitoes, these fish have been stocked in backyard ponds—subsequently spreading to nearby creeks and rivers during heavy rains. To avoid the spread of invasive fish in our natural environment, we encourage backyard pond users to stock native fish, such as pacific blue eyes, rainbowfish and hardy heads.

White clouds may be kept in an aquarium, but are not to be released or kept in outdoor ponds where they could wash out during high rainfall. If you catch these fish in the wild, you must not return them to the water.
