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...

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...

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...

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...

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 is not in the aquarium trade though is maintained by a few private collectors. It can be distinguished from all other members of the genus by the following combination of characters: first dorsal-fin withfirst dorsal-fin elongate in males; anterior portion of body with loosely-arranged ctenoid scales; head, entire nape to first dorsal-fin base, pectoral base, and belly naked; male colour pattern comprising creamy-yellow anterior portion of body with dark blotch at midbody and bright orange/red in postero...

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 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 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 not often seen in the aquarium trade and is apparently rare in its natural waters, with the occasional individual imported as bycatch in shipments of S. pulchra or S. robusta, or by private collectors. Like others in the genus it has a highly flexible, sinuous body which makes it very interesting to observe. It's told apart from congeners by the following combination of chara...

At the type locality of the congener S. lixianjiangensis sympatric species included Balitora kwangsiensis, Glyptothorax quadriocellatus, Garra orientalis, Hemibagrus pluriradtus, Poropuntius huangchieni, Pseudecheneis paviei,...

This attractive species is often seen for sale at around 3-4" in length (often as Hypostomus cf. emarginata or H. emarginatus), but given its adult size, its not a terribly good choice for the general community tank. Due to its very wide natural distribution, there are a number of known geographical variants, and this has resulted in four L numbers currently being assigned to it. In reality, there are many more variants than this, and all share the characteristic elongated which gives rise...

This species is sometimes referred to as Hypostomus villarsi, and is a rare find in the hobby. If you're lucky enough to see some for sale, check the fish have rounded bellies and that their eyes aren't sunken before you part with any cash, as these are classic signs of emaciation in newly imported Loricariids....

An easily kept cichlid whose character more than compensates for its somewhat drab colouration, S. casuarius is sometimes seen for sale as "Humphead", "Lionhead" or "Buffalohead" cichlid. It is a reophilic fish meaning it inhabits fast waters. Its swimbladder is modified to reduce buoyancy and thus prevent it from being swept away by the strong currents in it's natural habitat. In the aquarium it spends most of it's time resting on the substrate or hiding ...

S. tinanti has a confused taxonomic history, having been previously classified in the genera Gobiochromis and then Leptotilapia, before being assigned to Steatocranus. Further taxonomic revision is likely, as it exhibits both behavioural and morphological differences to other species in the genus. It is a reophilic fish, meaning it inhabits fast waters. Its swimbladder is relatively small to reduce buoyancy and thus prevent it from being swept away by the strong currents in its natural habita...

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...

This species is available occasionally, though not always under the correct name. We've seen it on sale as S. elegans on numerous occasions, for example, and other trade names include 'Sumatran blue neon goby' (it's not found on Sumatra), 'cobalt blue goby' and 'freshwater neon goby'. Further...

Because of it's its tiny natural range, habitat destruction due to excess water removal (the nearby town of Kumba relies on the lake for it's water supply), deforestation, the introduction of non-native species and overfishing, it is considered to be critically endangered. All efforts at captive breeding are to be encouraged. However, it is correspondingly rare in the hobby. The area around Lake Barombi Mbo has been suggested to be designated a protected area, but as yet this has not o...

The genus Sundasalanx is distributed throughout much of Southeast Asia and currently comprises seven species which have primarily been distinguished on the basis of oral and dental morphology, gill rakers and eye size. S. microps possesses 0-3 small conical teeth on ceratobranchial 5, 0-2 minute gill rakers on the first arch and a small eye measuring less...
