Hydrilla, a plant native to Central Africa, was widely used in home aquaria. Hydrilla was often dumped with aquarium water into drains, sewers, or ponds. It then thrived and has become an invasive species, disrupting aquatic ecosystems from Florida through the northeast United States. Removing Hydrilla from these ecosystems will most likely require either physically removing it or adding chemicals to the affected waters to kill it.
