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]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
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.
This common name is used for three different species of schooling fish with similar patterns: Hemigrammus rhodostomus, Hemigrammus bleheri, and Petitella georgiae. Splash tetra: Copella arnoldi: 5.5 cm (2.2 in) Spotted splashing tetra: Copella meinkeni: 4.5 cm (1.8 in) Pyrrhulina spilota: 7 cm (2.8 in) Serpae tetra: Hyphessobrycon serpae: 4.5 ...
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]
Unlike higher plants, algae lack roots, stems, or leaves. They can be classified by size as microalgae or macroalgae. Microalgae are the microscopic types of algae, not visible to the naked eye. They are mostly unicellular species which exist as individuals or in chains or groups, though some are multicellular.
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
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.
