Schistura species are omnivorous although the bulk of their diet consists of small insects, worms, crustaceans and other zooplankton with only relatively small amounts of plant matter consumed, mostly via the stomach contents of prey items. In the aquarium they will acc...

The identity of this fish is somewhat unclear although it's available in the aquarium trade on an occasional basis. It's been considered to represent various species including Schistura beavani, S. montana and S. himachalensis but there exi...

The identity of this fish is unclear but it has been traded as Schistura scaturigina M'Clelland, 1839 but does not appear to be that species based on its original description plus Vishwanath and Laisram (2001). The latter describe S. scaturigina as possessing a yellowish-white body with 12 transverse, triangu...

This species' distribution is unclear although individuals from the aquarium trade are said to have been collected in the Tenasserim river basin in Tananthayi Region, southern Myanmar. Type locality is 'supposedly from Tananthayi district, Tananthayi River basin, obtained dead from aquarium fish vendor at Meik'.

This species exhibits some interesting behaviour including a degree of social interaction plus the ability to cling to vertical or overhanging surfaces. It's sometimes sold under the name 'serpent loach'. The genus currently contains just three members all of which are known only from the Mekong basin. S. octozona is the type species and separated from the others mainly by body patterning which consists of 7-8 dark bars on each flank, these extending the full depth of the body and much wider than the pale interspaces between.

S. elongatus is known as "Caribe Pinche" in its native countries and is a rare find in the trade, tending to be quite expensive as a result. Individuals seem to vary in personality. While some are particularly fearless and will actively chase and attempt to bite hands or fingers placed in or up against the aquarium, others will always appear to be shy and nervous. The streamlined body form that gives rise to the species name is unique among serrasalmids, and has probably developed as a...

This species occasionally appears in the ornamental trade where it is sometimes referred to as 'blue tiger piranha' Following Fink and Macaht can be distinguished from other members of the genus by the following combination of characters: body shape deep and rhomboid; head robust, snout blunt; eye large; mouth moderate, jaw projecting; 1-3 ontogeneticlly var...

S. maculatus is one of the better choices for aquarists new to this group of fishes. It grows to a manageable size, is relatively hardy, attractive and usually quite inexpensive. It's sometimes referred to by the alternative vernacular names "gold piranha" or "golden mac" in the hobby. There are in excess of 30 described species of Serrasalmus many of which appear superficially similar and have confusing taxonomic histories. S. maculatus and S. spilopleura have often ...

S. lineolata was first recorded by Diard over 150 years prior to its 'rediscovery' in the early-1990s. It became available to the aquarium trade in the mid-2000s and swiftly established itself as one of the more popular balitorids in the hobby due to its attractive body markings and ease of breeding. It's also sold under the names 'reticulated hillstream loach', 'Vietnamese hillstream loach' and 'gold ring butterfly sucker'. It's difficult to...

This is one of the more readily-available members of the genus and popularly referred to as S. sp. 'spotted' or S. sp. 'special'. It's superficially similar in appearance to S. albisuera but in that species body patterning consists of a network of irregular dark lines forming a complicated series of reticulations vs. many small, light spots on a dark background in S. sp. 'SEW01'. It's been suggested that these two may represent the same species but this...

This species first became available in early 2009 and was initially identified as S. breviventralis (Freyhof and Serov, 2000) because there is a clear space between the pelvic and anal fins and body patterning is vaguely similar to that species, and also appears quite similar to S. elongata (Roberts, 1998) and S. sp. 'SEW03'. It does not fully match the original descriptions of either, however, and therefore remains in need of identification.

This species first became available in early 2010 and sometimes appears on trade lists under the vernacular names 'Laos sucker' or 'Laos Sakura sucker'. It's distinguishable from other members of the genus by the following combination of characters: body spotted and without stripes; no concentric bands on paired fins; origin of pelvic-fin below origin of dorsal-fin; origin of pectoral-fin posterior to corner of mouth; pelvic fin reaching origin of anal fin; small elevated ...

Type locality is given as 'Boleling, northern Bali, Indonesia' which appears to correspond to modern-day Buleleng, but this species is currently understood to have a patchy but wide distribution with a range stretching westwards from the Marquesas Islands (French Polynesia), throughout much of Vanuatu, New Caledonia, the Solomon Islands, Papua New Guinea, Palau, Fiji, Indonesia, the Philippines, Japan, Taiwan, and most recently, southern mainland China...

This species is also sold under the vernacular names 'golden Chinese loach' and '12-banded Chinese loach'. Along with S. robusta it's the most commonly-traded member of the genus, and the two are often imported in mixed batches, presumably because they occur and are thus collected together in nature. Like most congeners it has a highly flexible, sinuous body which makes it very interesting to observe. S. pulchra can be differentiated from...

This species is also sold under the vernacular names 'golden Chinese loach' and '12-banded Chinese loach'. Along with S. pulchra it's the most commonly-traded member of the genus, and the two are often imported in mixed batches, presumably because they occur and are thus collected together in nature.

This species is rarely-seen in the trade due to a relative lack of commercial exports from the middle Yangtze basin. It looks very similar to S. pulchra but can be told apart by the fact it lacks irregular, brownish markings and spots on the side of the head (vs. present in S. pulchra), and like most congeners it has a highly flexible, sinuous body which makes it very interesting to observe.

This species is also known by the vernacular names "Hockey Stick Catfish", "Lima Shovelnose", "Chiripira", "Chucharón" and "Pico de pato". The genus Sorubim currently contains five recognised species. Of the others S. cuspicaudus is recorded from the parts of the Rio Essequibo, Rio Orinoco, Amazon and Lake Maracaibo basins, S. elongatus from the Rio Essequibo, Rio Orinoco Rio Mamore and Amazon and S. maniradii from the mid-to-upper Amaz...

The genus Sphaerichthys currently comprises four species with S. osphromenoides by far the best known in the hobby. It's easily distinguishable from the congeners S. vaillanti and S. acrostoma since both exhibit a notably more elongate head and body profile, reverse sexual dimorphism (i.e. females are the more colourful/strongly-patterened), and are paternal mouthbrooders.

Known only from the Ryukyu Islands, Japan, and thus far recorded from just 4 streams on Okinawa island and two on Iriomote island. The type series derived from both islands with Okinawa given as type locality. It may be more widely-distributed than this however, and was possibly transported to the Ryukyu Islands via the Kuroshio Current, an ocean current similar to the Gulf Stream transporting warm, tropical water northward from an area east of Taiwan past Japan towards the polar region.

Type locality is given as 'Stream at end of long narrow bay, Waigeo Island, Irian Jaya, Indonesia', with the species also known from rivers draining the northern slope of New Guinea as well as Halmahera Island (Indonesia), the Admiralty Islands (Papua New Guinea), the Bismarck Archipelago (Papua New Guinea), D'Entrecasteaux Islands (Papua New Guinea), Louisiade Archipelago (Papua New Guinea), Bougainville (Papua New Guinea), Vanuatu, and...
