“It is alarming to know that zebra mussels are hiding in aquarium plants because these dangerous invasive species can easily take hold in Canadian waterways causing serious damage to native species and fisheries and can cause damage of more than $43 million a year to municipal water supplies, recreational boating, and other infrastructure,” says Gail Wallin, Chair of the CCIS. “Every aquarium owner must check their plants today to be sure they don’t have any invasive species, especially contaminated moss balls, in their aquariums.”
