Lebiasinidae
The pencil fishes are a family (Lebiasinidae) of freshwater fishes found in Costa Rica, Panama, and South America. They are usually small and are known as ornamental fishes in aquaria, including popular fishes such as the various pencil fish and the splashing tetra. Lebiasinids are small, cylindrical fish, ranging from in adult length. They prey on insect larvae, especially those of mosquitos. The family includes the voladoras (genera '' Lebiasina'' and '' Piabucina''), mostly found in highlands of the north Andes, the Guiana Shield and Central America, but the other species are mainly lowland fish inhabiting the Orinoco, Amazon and Paraguay River basins, and rivers of the Guianas. Genera Around 67 species are placed in these genera: Subfamily Lebiasininae - voladoras *'' Derhamia'' (one species) *'' Lebiasina'' (12 species) *'' Piabucina'' (9 species) Subfamily Pyrrhulininae, tribe Pyrrhulinini *'' Copeina'' (two species) *''Copella'' (9 species) *'' Pyrrhulina'' (17 speci ...

Pencil Fish
''Nannostomus'', (from the Greek: ''nanos'' = small, and the Latin: ''stomus'' = relating to the mouth), is a genus of fish belonging to the characin family Lebiasinidae. All of the species in this genus are known as pencil fish or pencilfish, a popular name that was first only applied to two species in the 1920s, ''Nannostomus unifasciatus'' and ''Nannostomus eques'', but by the late 1950s would come to be applied to all members of the genus."Exotic Aquarium Fishes" by Dr. William T.

Pyrrhulina
''Pyrrhulina'' is a genus of freshwater fishes found in tropical South America. Several of these species are popular aquarium fish. ''Pyrrhulina'' is closely related to '' Copeina'' and ''Copella'', although it is distinguished from the former by having only one row of teeth (''Copeina'' spp. have two). When the genus ''Copella'' was established, many species were removed from the genus ''Pyrrhulina'' and placed there, because differences in the maxillary bones in the males had been detected. ''Copella'' species are slimmer and more elongated than those species that remained in the genus ''Pyrrhulina''. Species The 18 currently recognized species in this genus are: * '' Pyrrhulina australis'' C. H. Eigenmann & C. H. Kennedy, 1903 * '' Pyrrhulina beni'' N. E. Pearson, 1924 * ''Pyrrhulina brevis'' Steindachner, 1876 * '' Pyrrhulina eleanorae'' Fowler, 1940 * '' Pyrrhulina elongata'' Zarske & Géry, 2001 * '' Pyrrhulina filamentosa'' Valenciennes, 1847 * '' Pyrrhulina laeta'' ...

Copella (fish)
''Copella'' is a genus of freshwater fish belonging to the family Lebiasinidae, native to South America, known colloquially to aquarists as splashing tetras or splash tetras, because of the unique reproductive method of the best-known representative of the genus, ''Copella arnoldi''. They are not as closely related to the tetras proper in the Characidae as initially believed. ''Copella'' species are found in assorted slow-moving tributaries in the Amazon basin, Orinoco and The Guianas. Description These fish are elongated in shape, with scales marked in such a way as to make visual differentiation of individual scales easy by simple naked-eye observation. The pectoral fins are positioned immediately behind the Operculum (fish), operculum or gill cover, while the pelvic fins are further back along the body, about midway between the head and the caudal peduncle. The dorsal fin is positioned above and slightly behind the pelvic fins, and midway between the pelvic fins and the tail f ...

Nannostomus Trifasciatus
''Nannostomus trifasciatus'', (from the Greek: ''nanos'' = small, and the Latin ''stomus'' = relating to the mouth; from the Latin: ''trifasciatus'' = three bands),"Exotic Aquarium Fishes" by Dr. William T. Innes, Innes Publishing Co, Philadelphia, 1935 commonly known as the three-lined or three-stripe pencilfish, is a freshwater species of fish belonging to the characin family Lebiasinidae. They are popular in the aquarium trade due to their small size, beautiful color pattern, and relative hardiness. Taxonomy Steindachner first described the species in 1876, making it one of the first four species in the genus to be described. As a result of the broad distribution of ''N. trifasciatus'', the species is polymorphic and, over the years, some of these color morphs have been erroneously described as separate species. ''Poecilobrycon erythrurus'' and ''Poecilobrycon vittatus'', two such examples, are now known to be junior synonyms. Distribution and habitat ''N. trifasciatus'' ...

Derhamia
''Derhamia hoffmannorum'' is a species of freshwater fish endemic to Guyana, where it is found in the Mazaruni River The Mazaruni River is a tributary of the Essequibo River in northern Guyana. Its source is in the remote western forests of the Pakaraima Mountains and its confluence with the Cuyuni River is near Bartica. As it descends from the Guiana Highlands .... It is the only species in its genus. It is found in fresh water at pelagic depths in a tropical climate. The average length of an unsexed male is about 6.1 cm (2.4 in). It has an elongated body with large eyes. It is a timid species compared to other similar species such as the various pencilfish. They live near the surface of water and are known to hide whenever possible, usually under floating objects. This species only eats what can be found at the surface, as well. ''D. hoffmannorum'' will not seek food that sinks to the bottom. The fish is named in honor of Peter Hoffman and Martin Hoffman (Salz ...

Splashing Tetra
''Copella arnoldi'', commonly known as the splash tetra or the splashing tetra, is a species of tropical freshwater fish belonging to the family Lebiasinidae. It is native to South America. The fish is named in honor of German aquarist Johann Paul Arnold (1869-1952), who collected the type specimen. Description The splash tetra is a small, slender fish with a standard length of . The mouth is relatively large and upturned, with acutely pointed teeth; this contrasts with the more horizontal mouth of the rather similar pencil fishes (''Nannostomus''). The maxillary bones are curved in an S-shape and the nostrils are separated by a ridge of skin. There is a dark spot on the dorsal fin and a dark line from the snout to the eye, which may continue to the operculum. There is no lateral line and no adipose fin. Distribution and habitat The species is endemic to tropical river basins in South America where it is present in river systems from the Orinoco to the Amazon River. It is found ...

Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Paraguay River
The Paraguay River (Río Paraguay in Spanish, Rio Paraguai in Portuguese, Ysyry Paraguái in Guarani) is a major river in south-central South America, running through Brazil, Bolivia, Paraguay and Argentina. It flows about from its headwaters in the Brazilian state of Mato Grosso to its confluence with the Paraná River north of Corrientes and Resistencia. Course The Paraguay's source is south of Diamantino in the Mato Grosso state of Brazil. It follows a generally southwesterly course, passing through the Brazilian city of Cáceres. It then turns in a generally southward direction, flowing through the Pantanal wetlands, the city of Corumbá, then running close to the Brazil-Bolivia border for a short distance in the Brazilian states of Mato Grosso and Mato Grosso do Sul. From the city of Puerto Bahia Negra, Paraguay, the river forms the border between Paraguay and Brazil, flowing almost due south before the confluence with the Apa River. The Paraguay makes a long, gentle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
