Species may be unintentionally disseminated through spores and fragments that hitchhike on ornamental fish and plants purchased from aquarium suppliers. [1] Algae is typically considered a nuisance and subject to removal through the use of algicides and the release of algae eaters. However, total elimination of algae is considered unlikely in a ...
