For many years this species has (and still is) imported as Pelteobagrus ornatus. It was assigned to the new genus Hyalobagrus, and discovered to be a distinct species, during a taxonomic revision of the Bagridae family in 1998. The other 2 species which were also thought to be P. ornatus are H. leiacanthus and H. ornatus. Apparently these two are imported rarely, if ever.

Unlike the vast majority of catfish, H. flavus is a diurnal species, and spends much of its time swimming in shoals in m…

This species is an infrequent import. It is very common in it's native countries, where it is used as a food fish.

This occasional import is sometimes offered for sale as P. ranga, the Indian glass fish. Unlike that species however, P. siamensis is an exclusively freshwater fish and should never be kept under brackish conditions. It can be distinguished from ranga by the lack of patterning behind the eye and it's generally more elongate body….

Previously known as Chanda ranga, the common name of this species arose because it's translucent skin means that the bone structure and internal organs are clearly visible. For many years it has been artificially injected with luminous dyes on fish farms in Asia and then sold as "Painted" glass fish or "Disco fish". This abhorrent act involves injecting the fish repeatedly with a large needle and most fish do not survive more than a few months afterwards. Whilst painted …

Apistogrammas are identified by the use of "A numbers"in a similar fashion to the "L number" system used to identify loricariids. Apistogramma brevis is identified as A168. Additionally, apistos are also grouped into type families and this species is the species type of the brevis group.

Unlike some apistogramma species, a. brevis occurs only in a relatively small range and has not been found outside this.

A new species that was only described to science in 2003, little is known about the natural behaviour of P. pulcinella. It has started to be imported quite regularly over the last couple of years, although it is still quite expensive. Unfortunately this species has suffered the same fate as some of it's close relatives, and artificiallly dyed specimens have been making their way onto the market. These should be avoided at all costs, as the processes involved are cruel and unecessary, and us…

This species has been exported for the aquarium hobby and ranks among the smaller members of the family. It can be differentiated from all other Akysis species by the following combination of characters: head length 22.0-28.6% of standard length (SL); caudal peduncle depth 8.8-10.7% of SL; anal-fin base length 15.2-19.1% of SL; eye diameter 12-16% of head length (HL); nasal barbel length 57 92% of HL; posession of 3-4 serrae on the posterior edge ofspine; body patterning mottled with indistinct …

This is the most commonly-encountered representative of the genus in the aquatic trade though is by no means common. As in other members of the genus body colouration is highly variable, even among individuals collected from a single locality, although a few useful regularities have been observed which can be used to distinguish certain species. This is thought related to the fact that Acrochordonichthys spp. periodically shed their skins and appear paler post-moulting.

Localities known in the hobby include ‘Pastaza’, ‘Putumayo’, ‘Requena’, ‘Río Nanay’, ‘Rio Napo’, ‘Maniti’, ‘Momón’, ‘Río Tigre’, ‘Río Ampiyacu’, ‘Shishita’, ‘Shushupi’, ‘Yavari’, ‘Tefé’, ‘Manaquiri’, ‘Lago do Januari’, ‘Mamori’ (often misspelled ‘Mamuri’), ‘Careiro’, ‘Manacapuru’, ‘Juruá’, ‘Curuaí’, and ‘Purutu’ though we’ve been unable to find anywhere matching the latter name within the species’ known distribution, and in fact several of these names are applied incorrectly on a regular basis.

A very cute little catfish, that unfortunately is rarely kept in ideal conditions. When it is maintained properly, it's a joy to watch as it feeds from close to the water surface, swimming frantically in the flow. It was reclassified, and placed in the genus Centromochlus in 1998.
