Talking Catfishes

This species was previously thought to be, and is often still sold as, A. hancockii, a name currently considered synonymous with Platydoras hancockii (Valenciennes 1840). It's also known by the vernacular names of blue-eyed catfish or Hancock's doradid, and in many ways is an ideal beginners' catfish, being hardy and tolerant of a wide range of water conditions...

This species, which may also be referred to by the alternative vernacular names 'spiny catfish', 'painted talking catfish' or 'chocolate raphael', isn't particularly common in the trade and most often exported only as bycatch among shipments of Platydoras armatulus. It appears very similar to the congener A. spinosissimus with the most useful external distinguishing character being the presence of pale blotches on the dorsal surface, between the dorsal and caud...

This species, which may also be referred to by the alternative vernacular names 'spotted raphael', 'white-spotted' or 'white-barred' catfish, is very common in the trade and despite its adult size is recommended to beginners and experienced aquarists alike since it is hardy, attractive and relatively-long-lived. The light body markings are highly variable in terms of exact placement and may be either white or pale to darkish yellow in colour. It is very similar i...

This species can be quite delicate when first imported, but once settled is usually quite hardy. When buying the fish, check that it has a rounded belly and that its eyes aren't sunken. These are classic signs of emaciation in newly imported specimens, and fish in this condition do not often survive for long. If you can find healthy specimens for sale, it is a charming addition to the larger community tank. It is superficially similar to the closely related Nemadoras leporhinus. The two ...

The genus Leptodoras currently contains 10 species, none of which are particularly well known in the hobby. There is little published information regarding the genus, and its members are seldom exported for the aquatic trade. L. linnelli is no exception, usually only turning up as bycatch among shipments of other species such as Opsodoras leporhinus or Hassar orestis. According to Fishbase, it can be distinguished from all other members of the genus except L. acipenserinus by the presence of...

Ther are currently five described species of Nemadoras (N. elongatus, N. hemipeltis, N. humeralis, N. leporhinus and N. trimaculatus). All are rare in the hobby, although this species is the one most commonly seen. As well as the occasional import, it sometimes shows up as bycatch among batches of similar-looking Hassar or Hemidoras species. Of these, it is most often confused with Hemidoras stenopeltis. These two can be easily told apart as N. leporhinus has a clearwith a dark patch at the base...

This popular species is also sold as the striped dora, striped raphael or striped talking catfish. It's often seen as an ideal beginner's cat, being hardy and tolerant of a wide range of water conditions. However its secretive nature, adult size and tendency to snack on smaller tankmates mean it should only be considered for communities of larger fish. The 'talking catfish' moniker is derived from the fish's ability to produce sounds when communicating with conspecif...

At present there's not a great deal of information available regarding this species. It seems to be fairly easy to keep, and makes a good addition to larger community tanks.

An interesting but rare species in the hobby, R. woodsi is nicknamed the "parrot doradid" due to its inquisitive feeding habits, and the curious bony growth extending from the upper mouthparts. The precise use of the bony growth isn't known, although one theory suggests it provides protection for the delicate barbels. Another hypothesis considers that it's some sort of feeding tool, possibly being used to lever aquatic invertebrates from crevices in submerged logs and roots....

A rare sepcies in the hobby that is seldom offered for sale.

This species is also known by the vernacular name "ripsaw catfish" (U.S.) and was often referred to by the scientific name M. irwini, now considered a junior synonym of M. uranoscopus, in older literature. Within the family Doradidae the genus Megalodoras is considered most closely-related to Lithodoras, Centrodoras and Platydoras, respectively. Members of the family Doradidae can be distinguished from all other Siluriformes by possession of a unique infranuchal scute, a dermal bon...

Previously referred to a Pseudodoras niger, the Ripsaw Cat is a fish only for the experienced fishkeeper due to its large adult size. Although a visually stunning fish, realistically, it is best suited to public aquaria. Much more peaceful than its common name suggests, which it gets from the spines that run down the lateral line of the fish. This fish is becoming more readily available to the hobby and prices are also falling, meaning that many fishkeepers are being tempted into buying a fis...
