Keep an eye out for exotic pests hiding in your aquarium.
Marimo moss balls are a popular live algae often used to decorate aquariums and water features. While pretty, they could be hosts to zebra mussel.
Zebra mussel is a prolific invasive pest that is exotic to Australia. If it becomes established in our rivers and lakes, it can force out native species, alter water quality, block pipes and foul aquatic infrastructure. The sharp shells can also injure swimmers and pets.
Zebra mussel can attach to live aquarium decorations such as plants and marimo moss balls.
If you've purchased marimo moss balls, learn how to check them for zebra mussel and secure any you may find. It's easy to report suspect aquatic pests and diseases to your state or territory biosecurity department.
When buying plants, animals and decorations for your aquarium or water feature, make sure you are buying permitted species from reputable sellers in Australia. Inspect all live products for unwanted pests and diseases.
Our zebra mussel information page tells you how to know if sellers are reputable, and how to tell if you have zebra mussel in your tank.
