This fish was collected for the aquarium trade during 2012 but its identity has not yet been established. The fish in our images were obtained at an unspecified locality in the Garo Hills, these for...

This fish was collected for the aquarium trade during 2012 but its identity has not yet been established. Schistura is the most species-rich genus among nemacheilid loaches with some 190 members and it continues to grow with over 100 having be...

Known from minor rivers in the coastal states of São Paolo, Paraná, and Santa Catarina, southern Brazil, plus some tributaries of the rio Paraná basin in Paraguay. Type locality is 'Paranaguá, 25°32'S, 48°36'W, Paraná, Brazil'.

Although S. jardinii superficially resembles its Asian cousins, it is not considered as desirable an aquarium inhabitant, nor is it classed as being at risk in nature. It can be easily distinguished from the asian species by its much smaller scale size, greater lateral scale count (32-35 as opposed to 21-25 in the asian aros) and duller patterning. It differs from its Australian relative S. leichardtii by its more sloping head, downward-pointing barbels and patterned gill covers. The base colour...

Although S. leichardtii superficially resembles its Asian cousins, it is not considered as desirable an aquarium inhabitant, nor is it classed as being at risk in nature. It can be easily distinguished from the asian species by its much smaller scale size, greater lateral scale count (32-35 as opposed to 21-25 in the asian aros) and duller patterning. It differs from its Australian relative S. jardinii by its spotted scales, forward-pointing barbels, lack of sloping head and unpatterned gill cov...

S. altuvei is very scarce in the hobby, most commonly being found among imports of juvenile S. rhombeus (the type species of the genus). It's also known as the "Caribe azul" or "blue caribe" in the trade. There are currently 24 described species of Serrasalmus, many of which look superficially similar. This one is considered a member of the "compressed group". This grouping of morphologically similar species currently comprises S. altuvei, S. geryi, S. compress...

S. geryi is sometimes sold as the "violet-line piranha" in reference to the unusal purple stripe that runs from the base of the lower jaw over the top of the body. It makes a stunning aquarium fish as it also possesses highly reflective scales, deep orange/red eyes and a compressed, high-bodied shape. Far from widespread in nature or the hobby, it tends to be pricey and highly sought-after when available. There are currently 24 described species of Serrasalmus, many of which look s...

There are currently 24 described species of Serrasalmus, many of which look superficially similar. S. marginatus has at various times been considered a synonym of S. rhombeus and S. humeralis, but is currently considered to be distinct. It's main distinguishing feature is usually given as the thick, black, v-shaped marking in the anterior portion of the caudal fin. Juveniles are said to differ from similar-looking species such as S. compressus and S. altuvei because the dark body "spot...

There are currently 24 described species of Serrasalmus, many of which look superficially similar. S. sanchezi has frequently been confused with S. spilopleura in the past, and is sometimes still sold as "Spilo cf" or "Ruby-red Spilo". It actually appears to be more closely related to S. rhombeus or S. irritans than S. spilopleura. The characteristic red throat has also led to it being confused with S. medinai and even the red-bellied piranha Pygocentrus nattereri on occasion...

There are currently 24 described species of Serrasalmus, many of which look superficially similar. S. serrulatus occupies a particularly confusing taxonomic position and is very tricky to identify positively. According to scientific literature it is very close in appearance to several congeners, most notably S. eigenmanni, S. hollandi, S. humeralis and S. nalseni. The separation of these is largely based on geographical range and it's possible that some of them may turn out to be synonymous...

This species appeared in the trade during 2010 and its identity has been confirmed to us by Thai exporter and aquarist Kamphol Udomritthiruj who collects it from the Se Kong system for the aquarium hobby. To date only subadult specimens have reached the western market.

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 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 ...

The fused pelvic fins form a structure normally referred to as the 'pelvic disc', a common feature among gobiids which is used to adhere to rocks and other submerged surfaces. In Sicyopus, as in Stiphodon, this is short-based and attached to the belly only between the fifth pair of fin rays whereas in other sicydiines it's attached between all five rays (Watson, 2005).

This species has a somewhat confusing taxonomic history and it remains unclear whether it is conspecific with S. izecksohni (Da Cruz, 1983) or not. The latter is considered to represent a synonym of S. myersi by Costa (2007), but the majority of authors do not follow the conclusions of that study (see below) and continue to view both as valid.

This species is traded as S. sp. 'rainbow', S. sp. 'gold fin', or S. sp. 'gold cheek' and is among the more widely-available members of the genus although its identity was unclear prior to 2013. The most commonly-traded fish certainly appears to...

This species is not traded commercially at present and the specimen pictured above was brought back from northern Papua New Guinea by private collectors in 2008. It's diagnosable from other members in the genus by possession of 10 segmented rays in the second dorsal fin, males with filamentous spines in the firstandusually with 14 rays. Colour patterning in males is also distinctive (see 'Sexual Dimorphism'). The Gobiidae is the most speciose vert...

This species was initially described as Rasbora axelrodi and is referred to as such in older literature, but in 1999 was moved into the new genus Sundadanio where it remains the monotype. Its wider placement within the family Cyprinidae is still not fully resolved. Following Rüber et al. (2007) it is most closely-related to the miniature species of the genus Paedocypris, the two genera characteristically lacking bones in the roof of the skull as well as exhibiting genetic similarities. Howe...

This species was described from a single specimen and included in the genus Leporinus until 2011 at which point the holotype was examined and recognised as corresponding to the fish described as Synaptolaemus cingulatus (Myers & Fernández-Yépez, 1950).

A very nocturnal species that will be seen only infrequently during daylight hours. S. angelicus is very long-lived and can survive for over 20 years if maintained correctly. S. angelicus was much sought after when first imported and commanded a correspondingly large price. They are still relatively expensive, though prices have dropped considerably. It is quite a rare species in its native waters. The patterning and colour varies cosiderably, depending on type locality. Some specimens have w...
