This species is very rare in the aquarium hobby and may never have been available on a commercial basis although it has been collected, bred and distributed by some private collectors. It's a member of the putative G. surinamensis 'group' of closely-related species within the genus and ca...

This species was available in the hobby several years prior to being described, invariably traded as G. sp. aff. altifrons 'Tocantins', G. sp. 'Tocantins' or G. sp. 'rio Areoes'. The latter of these names refers to an Indian reserve named 'Areões' in the rio Das Mortes drainage, a tributary of the Araguaia which itself drains into the Tocantins, and the aquarium specimens in our images have been identified as G. neambi by Dr. Paulo Lucinda, co-describer of the species.

This species was introduced into the aquarium trade in the early 20th century but disappeared soon after. It subsequently reappeared in a Berlin zoo in 1965 and has been available from specialist breeders ever since. It occasionally appears for sale in aquatic shops....

Not a good beginner's species, due to its very respectable adult size, but it makes a stunning oddball addition to communities of larger fish. It's sensitive to many aquarium medications, particularly those containing copper. The genus Gymnotus has undergone considerable taxonomic revision in recent years, with over 20 new species being described since 1994, including several that were originally considered to be G. carapo. The systematics of the genus are still not fully understood...

This species is among the most well-known fishes in the aquarium trade but juveniles are typically being offered for sale with little to no information regarding temperament, eventual size, and potential age in excess of 15 years. Wild examples are not currently traded, with all of those seen on sale produced on a commercial basis.

This species is traded under various vernacular names including 'ember barb', 'banded barb' and 'black spot barb', and is perhaps among the more undervalued small cyprinids in the aquarium hobby being peaceful, relatively hardy, colourful, and of interesting behaviour. It exists in a number of colour for...

The genus currently contains seven species of which H. macrolepidota and, to a lesser extent, H. dispar are the only ones seen with any regularity in the aquarium trade. As well as having the widest distribution H. macrolepidota is also the largest member of the group. All representatives can appear superficially similar at first glance, the exception being H. lopezi which is endemic to a single island in The Philippines and displays a unique lateral band-like marking on the flanks.

This species is also known by the vernacular 'jungle perch' or 'sidebar barb' and should not be considered an aquarium subject in all but the most extreme circumstances since it can grow to over 2 feet in length, weigh in excess of 5 kg and is a powerful, pelagic predator. It's also a popular sport fish with a reputation for striking hard.

This species is poorly-known in the aquarium hobby and may have never been maintained outside its native countries. It can be distinguished from congeners by the following combination of characters: 26-27 lateral line scales; two roundish, dark blotches on each flank, one beneath dorsal-fin origin and above the lateral line, the other on the caudal peduncle and passing thro...

The pinkish-white form of this species is among the most widely-traded aquarium fishes in the world but does not occur naturally and is in fact a leucistic variant bred specifically for ornamental purposes. The 'short-bodied' or 'balloon' variety also continues to be fashionable but under no circumstances do we recommend the purchase of these intentionally disfigured animals which tend to have much shorter life spans than the naturally-shaped fish. There also exists a less-po...

This species appears to be unknown in the aquarium trade but is a valued food fish within its native range. Hemibagrus has been divided into a number of putative species groups which may or may not represent monophyletic assemblages, and following a major review by Ng and Kottelat (2013) H. filamentus is included in the H. nemurus group.

This species cannot be considered a suitable home aquarium subject given its eventual size plus the fact it can live for several decades. It can be told apart from most oth...

This species is relatively common in the aquarium trade but has been widely misidentified as the congener H. nemurus which is native to Java and may never have been exported for ornamental purposes. Hemibagrus has been divided into a number of putative species groups which may or may not rep...

Hemiodus species can be a very skittish when first introduced to the aquarium, but usually settle down over time, especially if a large number are being kept together. All of them look superficially similar, but can be distinguished by differences in patterning. None are particularly common in the hobby....

Hemiodus species can be very nervous when first introduced to the aquarium but usually settle down over time, especially if a large number are being kept together. All of them look superficially similar, but can be distinguished by differences in patterning. None are particularly common in the hobby, but H. gracilis is probably the most often seen. It is sometimes sold as the red or red-tailed hemiodus and was previously considered a member of the now defunct genus Hemiodopsis....

Hemiodus species can be a very skittish when first introduced to the aquarium, but usually settle down over time, especially if a large number are being kept together. All of them look superficially similar, but can be distinguished by differences in patterning. None are particularly common in the hobby. H. ternetzi can be identified by the fact that the black lateral stripe extends to behind the eye, and thehas no pigmentation....

The only species in the genus, and a popular game fish in its native range, H. odoe superficially resembles our native European Pike. It is an ambush predator with a fearsome set of teeth, and should be handled very carefully, particularly when maintaining its tank. Although juvenile specimens have become relatively common in the trade in the last few years, this is strictly a species for the specialist who is able to provide it with a suitably large aquarium and the correct conditions. In sm...
