Aquariums and water gardens add beauty and tranquility to our homes. Many plants and animals that we use in aquariums and backyard ponds have been imported from other parts of the world. While they are excellent to enjoy they may be harmful to Michigan's native ecosystems if they are released into the wild. Although Michigan’s winter temperatures stop some exotic species from reproducing in our lakes and streams, this is not always the case. Some species survive and thrive, negatively impacting the environment, decreasing recreational opportunities and causing severe economic consequences.
It is never safe to release water garden or aquarium plants and animals into the natural environment, even if they appear to be dead.
Together we can keep Michigan’s waterways healthy and pure
- Never release an aquatic plant or animal into waterways
- Inspect and rinse any new plants to rid them of seeds, plant fragments, snails and fish.
- Build water gardens well away from other waters.
- Give or trade unwanted fish or plants with another hobbyist, environmental learning center, aquarium or zoo.
- Contact a veterinarian or pet retailer for guidance on humane disposal of animals.

Wildlife sightings, soothing sounds, and scenic beauty are just a few benefits from having a backyard water feature.
The Reduce Invasive Pet and Plant Escapes (RIPPLE) program offers information to aquarium and water gardener professionals, retailers and hobbyists about what to do with unwanted plants and animals so they are not introduced into Michigan's lakes and streams.

RIPPLE is funded by the Michigan Invasive Species Grant Program.
