This species of algae produces highly toxic extracts that are harmless toward smaller grazers including amphipods and polychaetes yet are capable of killing herbivorous reef fish. Death occurs within 10 hours of the algae's introduction to a well-aerated aquarium during which the fish will attempt to jump out. [18] 8 in (20.3 cm) [19]

Various examples of aquatic hitchhiking algae that may be found in freshwater aquaria. There are many types of algae that are commonly found in a freshwater aquarium setting. Species may be unintentionally disseminated through spores and fragments that hitchhike on ornamental fish and plants purchased from aquarium suppliers. [1]
Today, algae are used by humans in many ways; for example, as fertilizers, soil conditioners, and livestock feed. [124] Aquatic and microscopic species are cultured in clear tanks or ponds and are either harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is an important type of aquaculture in some places.
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, water hyacinth, and algae. [4] Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface.

Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon and producing at least 50% of Earth's oxygen. [3] Natural seaweed ecosystems are sometimes under threat from human activity.
