Endemic to Sri Lanka with type locality 'shaded pools of mountain streams at Akuressa, Southern Province, Sri Lanka, elevation 500 meters'. It's known from at least five localities, all of which are located in restricted to Sri Lanka's 'wet zone' in the southwest of the island, with records exis...

The family Cobitidae, often referred to as 'true' loaches, is widely-distributed across most of Eurasia with the Indian subcontinent, Southeast Asia and China representing particular centres of species diversity. Phylogenetic analyses by Tang et al. (2006), Šlechtová et al. (2007) and Šlechtová et a...

According to Kottelat (2012) L. manipurensis Arunkumar, 2000, which was described from Moreh, Manipur state, northeastern India, close to the border with Myanmar, is a syonym of L. micropogon. Havird and Page (2010) differentiate the two based on caudal-fin patterning, predorsal length and ver...

This fish has only been traded on a handful of occasions to date. It's been referred to as Lepidocephalichthys cf. hasselti and Lepidocephalus cf. thermalis but appears to be an undescribed member of the former genus. Following a...

This fish may only have been exported for aquaria on a single occasion to date. It exhibits characters reminiscent of both L. alkaia and L. guntea, and has been referred to as L. cf. guntea) but is most likely an undescribed species (Havird, pers. comm.).

This species is available sporadically and makes an excellent choice for those new to keeping loaches. It's distinguishable from congeners by a combination of characters including: truncate/rounded caudal-fin; no scales on top of head; dark, squarish spots o...

This species is not traded often but may be available occasionally bycatch among shipments of other species. It can be told apart from congeners most easily by the following combination of characters: truncate caudal-fin; scaleless patch on top of head; caudal-fin with reticulated patterning, sometimes appearing as a series of thin vertical bars; body reddish brown with darker markings; 3-7 predorsal and 3-6 postdorsal thin, transverse dark bars running across the dorsal surface; relatively deep...

The type locality consisted of remnant ephemeral pools in otherwise dry agricultural land, and many adults were collected from such habitats. Other species present included the congener L. hasselti plus members of Anabas, 'Puntius', Rasbora, Channa, and Hampala.

The distribution records for this species are somewhat confusing. It was described from the confluence of the Lamatang and Enim rivers, Palambang Province, Sumatra and has since been recorded from Thailand (Chao Phraya River), Peninsular Malaysia (Pahang River) plus the islands of Java (Solo River) and Borneo (Kapuas and Barito rivers).

Lungfish are among the most intriguing of "oddball" aquarium species, being able to survive in extreme conditions. They are very ancient fish, having remained virtually unchanged for millions of years. This is the only species known from South America, and is the sole representative of its genus. Most hail from Africa, with a single species native to Australia. They belong to the class Sarcopterygii (lobe-finned fishes), members of which are actually more closely related to terrestrial...

Known from Great Lakes Erie and Michigan with distribution extending south through the Mississippi River basin to the Gulf of Mexico drainages where it's said to occur between the lower Apalachicola River in Florida and the Nueces River in Texas. It may also be found in the Rio Grande which forms the border between Mexico and the United States further south where records include Falcon International Reservoir, for example.

A very stylish looking plec, L. galaxias can also be seen for sale as the vampire or tusken plec. Both these names relate to features of morphology that are shared by all members of the genus. The latter arose from the presence of a characteristic growth on the head of the fish. The vampire moniker, meanwhile, is derived from the unique upper jaw dentition, consisting of, you guessed it, two large teeth or "fangs". The exact use for these is unknown, but they're probably utilised ...

The vampire part of the common name is derived from the unique upper jaw dentition exhibited by members of this genus, consisting of, you guessed it, two large teeth or "fangs". The exact use for these is unknown, but they're probably utilised to grip prey items such as snails or other aquatic invertebrates in some way. When buying one of these (or any Loricariid), be sure to check the fish has a rounded belly and that its eyes aren't sunken, as these are classic signs of ema...

Leporacanthicus species are commonly referred to as "vampire plecs". This is derived from the unique upper jaw dentition exhibited by members of this genus, unsurprisingly consisting of two large teeth or "fangs". The exact use for these is unknown, but they're probably utilised to grip prey items such as snails or other aquatic invertebrates in some way. Another feature shared by all Leporacanthicus is a small bony growth of unknown use on top of the head. This particul...

There are a few different colour forms of this lovely suckermouth available, each of which possess varying amounts of orange patterning in the fins. Some of these are given extravagant sounding names such as "dragon fin" or "tiger fin". What's nice about this species, is that these flashes of colour don't fade with age, as with many of its relatives, making for a striking fish when fully grown. Leporacanthicus species are commonly referred to as "vampire ple...

Type locality is given simply as 'Amazon River, Brazil' and according to current thinking this species has a huge natural range encompassing the Amazon River system in Brazil and Peru plus the Paraná-Paraguay drainage in southern Brazil and Paraguay and rio São Francisco basin in southern Brazil. Specimens in our images were collected fro...

Type locality is 'Tukeit, Guyana', and this species is known from various river drainages of Venezuela, Guyana, Suriname and French Guiana including the Orinoco, Essequibo, and upper Courantyne (aka Corantijn) basins. Additional records exist from the upper Amazon basin in Guyana, these presumably corresponding to the Takutu river basin, itself part of the upper rio Branco.

Décor is relatively unimportant and maintenance simple provided sufficient space is available. A natural-style arr...

Type locality is giev as 'Rio Parahyba and tributaries at Mendez; Juiz de Fora; River Doce; River São Matheos; Rio Jequitinhonha; Rio Quenda at Santa Cruz', all of which pertain to localities within the Paraíba do Sul and Doce river systems in Minas Gerais, Espírito Santo, rio de Janeiro and São Paulo states, southeastern Brazil.

This species is also referred to as 'black-anded leporinus', 'striped leporinus' and 'eight-banded leporinus'. Young specimens are often traded for aquaria without warning as to their potential size and requirements, and as a result it's fairly ubiquitous in public aquarium displays.
