Cnesterodon decemmaculatus, the ten spotted live-bearer, is a species of poeciliid native to Argentina and Uruguay. [1] [2]
The original description by Jenyns (1843) was in "Fish" in Darwin, Charles (ed.), The Zoology of the Voyage of H.M.S. Beagle, during the years 1832-1836," London, pt. 4, 172 pp. [3]
The species name is Latin for ten-spotted, referring to the markings on the middle of the flanks. [4]
The body build is elongated, the head small and pointed. The base color is an olive to yellow. The belly is silvery. The flanks show a black band consisting of seven to eleven narrow vertical stripes. All the fins are colorless, except for some dull black edging on the dorsal and caudal fins under some conditions, which depends upon the moods of the fish. [5]
The males possess an angled, anterior placed gonopodium. Typical for the female is her bulging body that increases in size as the gestation progresses.
Cnesterodon decemmaculatus is found in Bolivia, Brazil, Paraguay, Uruguay, and Argentina, where it prefers calm waters with much aquatic vegetation, which are found in shallow streams and drainage ditches. These waters, which can be heated to 30 °C in the hottest season, is the norm.
This species is one that should be kept with its own kind. It does not mix well with other species, even other Cnesterodons. It can be kept in the smallest aquaria. The aquaria should be well planted, the water moderately agitated and a temperature of about 27o C. which seems to suit these fish just fine. Regular partial water changes round out their optimal care.
Diet is not a problem as long as the aquarist realizes that these fish can only manage to swallow the smallest morsels. It is advisable, therefore, to feed them only live foods such as Cyclops, Artemia and sieved pond food. As a supplement, they can be given the dry, almost dust like food usually fed to young fish. Keeping them in algae-overgrown tanks, too, has been very successful.
Such algae covered aquarium tanks, are not always a pleasant sight, so the young fish should be raised in a separate algae covered tank and not in the parent's aquarium itself. After a 24 days gestation period, from five to ten, and rarely up to 15, young are born, each measuring 2 to 2.5 mm. Sexual maturity occurs after the third or fourth month.
Marine angelfish are perciform fish of the family Pomacanthidae. They are found on shallow reefs in the tropical Atlantic, Indian, and mostly western Pacific Oceans. The family contains seven genera and about 86 species. They should not be confused with the freshwater angelfish, tropical cichlids of the Amazon Basin.
Sterba's corydoras is a member of the South American Corydoras genus of freshwater aquarium catfish and one of the most popular species of Corydoras due to its attractive markings. The fish is native to the Guaporé River region between Bolivia and Brazil.
Zebrasoma desjardinii, the Red Sea sailfin tang, Desjardin's sailfin tang, Indian sailfin tang or Indian sailfin surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This fish is found in the Indian Ocean.
Community aquaria are tanks that are designed to contain more than one species of fish. Most commonly they include a variety of species that do not normally occur together in nature, for example angelfish from Brazil, swordtails from Mexico, and gouramis from South East Asia. The aim of such communities is to bring together fish that are compatible in temperament and water requirements, while using their different colours and behaviors to add interest and entertainment value.
Poecilia wingei, known to aquarists as Endlers or Endler's livebearer, in the genus Poecilia, is a small fish native to the Paria Peninsula in Venezuela. They are prolific breeders and often hybridize with guppies. These very colorful hybrids are the easiest to find being offered in pet-shops, typically under the name Endler's guppy.
The Cauca molly is a freshwater fish in the family Poeciliidae. This fish is found in Panama, Venezuela, and Colombia, where it lives in shallow waters in the basins of the Lebrija, Magdalena, Cauca and other rivers. P. caucana eats mosquito larvae and algae.
The diamond tetra is a small freshwater fish of the characin family of order Characiformes. It is found in and around Lake Valencia in Venezuela, South America.
The convict julie is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika. Hence it is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The fish is named after Charles Tate Regan.
The Chiapas swordtail or upland swordtail is a species of livebearing freshwater fish of family Poeciliidae, and genus Xiphophorus. It is, therefore, in the same genus as the common platy and the swordtail. The Chiapas swordtail was discovered and first described by Donn E. Rosen in 1960, along with four other species of Xiphophorus.
Heterandria formosa is a species of livebearing fish within the family Poeciliidae. This is the same family that includes familiar aquarium fishes such as guppies and mollies. Heterandria formosa is not as commonly kept in aquaria as these species. Despite the common name "least killifish", it belongs to the family Poeciliidae and not to one of the killifish families. H. formosa is one of the smallest fish species; the 1991 Baensch Aquarium Atlas listed it as the 7th smallest fish in the world, and as of 2006 it remains the smallest fish species found in North America.
The redtail splitfin or redtail goodeid is a species of goodeid fish from the family Goodeidae and subfamily Goodeinae. Like other members of Goodeinae, the redtail splitfin is native to Mexico and a livebearer. However, the goodeid mating system differs in several ways from the more common livebearing fish from the family Poeciliidae that includes guppies and swordtails. While no goodeid species is a very popular aquarium fish, the redtail splitfin is one of the most popular. Only the male has the red-orange tail for which it is named. Its specific name honours the collector of the type, Gustav Eisen (1847–1940) who was Curator of Marine Invertebrates at the California Academy of Sciences in San Francisco, California.
The orange-spotted spinefoot, also known as the deepbody spinefoot, gold-saddle rabbitfish, golden rabbitfish, golden-spotted spinefoot, goldlined spinefoot or yellowblotch spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the eastern Indian Ocean and western Pacific Ocean. It occasionally makes its way into the aquarium trade.
The green swordtail is a species of freshwater/brackish fish in family Poeciliidae of order Cyprinodontiformes. A live-bearer, it is closely related to the southern platyfish or 'platy' (X. maculatus) and can crossbreed with it. It is native to an area of North and Central America stretching from Veracruz, Mexico, to northwestern Honduras.
The pike topminnow, more commonly known as pike killifish and sometimes referred to as topminnow, is a species of poeciliid found from Mexico to Nicaragua. It has also been introduced to Florida, USA. It is the only known member of its genus. The pike topminnow was described in 1860 by Austrian ichthyologist Rudolf Kner, who gave the type locality as Belize, which is reflected in this species' specific name.
Cnesterodon is a genus of poeciliids native to South America.
Alfaro cultratus, the knife livebearer, is a species of tropical freshwater fish from the family Poeciliidae. It hails from Central America and is often kept in home aquaria.
Scolichthys greenwayi is a species of freshwater fish of the family Poeciliidae. It is found in flowing waters along the Rio Chixoy and Rio Salinas system in Alta Verapaz, Guatemala.
Xiphophorus pygmaeus, the pygmy swordtail, is a poeciliid fish from northeastern Mexico. It is the smallest of the swordtails. The male's sword is barely visible and the species is often called the swordless swordtail. It is sometimes kept in home aquaria, but is a rather delicate species.
Cnesterodon carnegiei, commonly known as Carnegie's toothcarp, is a species of poeciliid native to southeastern Brazil and Uruguay.
Cnesterodon raddai, the Resistencia toothcarp, is a species of poeciliid native to the Paraguay and lower Paraná River basins.
