Freshwater Fish Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. It is situated in the middle of Indian Ocean. Because of being an island, Sri Lanka has many endemic freshwater fauna, including fish, crabs, molluscs, and other aquatic insects. Species List Class: Actinopterygii Freshwater fish are physiologically differ from marine and brackish water forms. The low salinity and high osmotic pressure makes them so different. Few fish can be found in all three ecological systems. There are 95 species of freshwater fish occur in the country, where 53 of those are endemic. 41% of all known species of fish of Sri Lanka are found in freshwater. There are about 70% of endemism of those fish. Most of them are listed into IUCN categories. Four ''Devario'' species were described in 2017 by Batuwita et al. However, the taxonomy and descriptions were cited as problematic by fellow local ichthyologists. Note: introduced species are not included in the list. Go to '' List of intro ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devario Malabaricus
The Malabar danio (''Devario malabaricus'') is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of rarely exceeds in a home aquarium. The Malabar danio is found in tropical climates in a wide variety of waters, from mountain streams to small pools, but it prefers flowing waters. It is an active, schooling fish that prefers to be in groups. Its diet consists of insects and plant matter. Malabar danios are oviparous, and spawn in shallow water after heavy rains among the plants growing on the bottom. An adult will spawn around 200 light-orange, sticky eggs that will hatch in one to two days. The fry will be free-swimming after the fifth day. The parents must be removed from aquaria to prevent them from eating the eggs. The species was earlier incorrectly considered a synonym of ''Devario aequipinn ...

Green Carplet
The horadandia, green carplet, or glowlight carplet (''Horadandia atukorali''), is a species of very small (maximum total length) cyprinid fish that is found in slow-moving or still fresh and brackish Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estu ... water habitats in western Sri Lanka. Earlier thought to be a monotypic genus with the single species found in both Sri Lanka and India, an analysis published in 2013 showed that the Indian population should be recognized as a separate species, '' Horadandia brittani''.

Garra Ceylonensis
''Garra ceylonensis'' (the stone sucker or Ceylon logsucker) is a species of ray-finned fish in the cyprinid family. It is endemic to rivers and streams in Sri Lanka (formerly known as "Ceylon") - and is considered as a schooling fish. It is a rheophilic species and occurs in slow to moderately flowing rivers and streams, and ascends small, rocky streams in order to breed. It primarily feeds on algae such as diatoms. Taxonomy A 2021 study found ''G. ceylonensis'' to be a sister species to the mullya garra (''Garra mullya'') from mainland India, which itself may comprise two species. ''G. ceylonensis'' comprises primarily six genetically distinct subclades that are each tied to a single river basin, albeit with two exceptions. Evolution The ancestor of ''G. ceylonensis'' colonized Sri Lanka from India once during the late Pliocene, via a former isthmus that existed in the Palk Strait, and from the Pleistocene until its submergence, the still-exposed isthmus may have had a h ...

Esomus Danricus
The Indian flying barb (''Esomus danrica''), historically flying barb, is one of the species known in the group flying barbs owing to their extremely long barbels. It was discovered as long ago as 1822 by Hamilton. However, it is rarely seen in aquaria. It is found in Myanmar, Nepal, Pakistan, Sri Lanka and India, it is found in many of the same localities as ''Danio rerio'' and ''Danio dangila'', an example being the Jorai Rivulet, a tributary of the Sankosh river in Coochbehar district, West Bengal, India. The rare fish Borellius spp. is locally named "Boirali maach". Description This fish reaches a maximum length of 6 in (15 cm). The Indian flying barb is a silver fish with a black line on an elongated body and gold fins. Barbels reach almost to the anal fin. Behaviour This fish has an exceptional ability for jumping, hence its name. Research in 2001 by Fang Fang suggests that ''Esomus'' is the genus most closely related to ''Danio'', closer even than ''Devario''. ...

The barred danio (''Devario pathirana'') is a fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka, this fish grows to a maximum length of 2 inches (6 cm). In the wild, the barred danio is understood to be critically endangered, but is freely available from captive-bred stock. Typically, the fish prefer water with a 6.0-8.0 pH, a water hardness of 5.0-19.0 dGH, and an ideal temperature range of 69-79 °F (20-26 °C). Its diet consists of annelid worms, small crustaceans, and insect Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs ...s.
