Results for “C number”

There are currently over 180 described species of Corydoras (commonly shortened to "cory"), making it one of the most speciose of all South American fish genera. There are also loads of undescribed species, many of which have been assigned a "C number" for identification purposes. This is a very simple system of numbering and is similar to the L number scheme used to identify undescribed Loricariids. Both systems were implemented by the German aquarium magazine DATZ (Die Aqua...

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby; to date it has only been exported in very limited numbers. It was for a number of years known as Badis badis siamensis and will be seen labelled as such in older literature. Within the genus it is most easily confused with B. khwae and B. ruber but can be identified by the flank patterning which consists of rows of horizontally-arranged dark markings. In B. ruber these appear mor...

The identity of this species was unclear for a number of decades prior to its redescription by Ng and Kottelat (2013). The confusion originated with Brittan (1954) who misidentified specimens of R. tornieri as R. dusonensis and was exacerbated by Alfred (1963) who concluded that the holotype of R. dusonensis was conspecific with R. myersi.

This species is readily available in the aquarium trade and is a good subject for those new to the hobby given its peaceable nature and relative adaptability in terms of water chemistry. It's sold under various names including A number of selectively-bred ornamental strains have also been produced including 'red', 'sunset', and 'golden', for which care is identical to the natural form.

This species is popular in the aquarium hobby and unlike the majority of congeners tends to spend a fair amount of time away from the substrate, often forming groups in midwater. It has been placed in the unofficial 'C. elegans group', which contains a number of species exhibiting similarities in morphology and colour pattern, some of which remain unidentified in scientific terms.

P. interruptus are quite sensitive to water quality and if a high standard is not maintained the development of the males' fins may be impaired and the fish will lose colour. They are also quite an easily frightened fish, particularly if they are not maintained in numbers. This species is most often seen for sale as a fairly drab, greyish 1 1/2" fish and is often overlooked. However once they are settled into the aquarium and have begun to mature they develop spectacular colouration. ...

Prior to description in 2011 this species was traded under the DATZ code numbers L018, L085, L077 and 'Das Aquarium' code LDA060, while a very similar-looking fish from the lower rio Xingu which has been assigned the code L081 may also represent a form of B. xanthellus but is not mentioned in the description paper. B. xanthellus can be distinguished from congeners by a combination of the following...

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....

There are currently eleven species in the genus most of which have previously been included in Puntius, Barbus and the now defunct genus Gonoproktopterus. Of these the only ones we've seen in the trade are H. jerdoni and H. curmuca although it's possible that others have been exported in small numbers or as contaminants among shipments of other species. Even these two are very rarely encountered and little has been written about the group as a whole....

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. personata complex gibbiceps group...

The Brycon genus is large, at present containing over 50 species. A number of these are very similar, a couple of which (B. rubricauda and B. orbignyanus) resemble B. cephalus quite closely. However this one is the most common in nature and is likely to be the species seen on sale most often. Commonly known as the matrinxã in Brazil, it has an interesting life cycle, migrating twice per year over large distances according to the season. The first movement occurs at the start of...

M. affinis was one of the first rainbowfish species to be imported for the hobby in any numbers. There are several geographical variants, three of which can be found in the hobby. The "standard" form has a large natural range and is the most commonly encountered. The "Pagwi" form has a very limited distribution, being known only from a tributary of the Sepik River in New Guinea, while the "Bluewater Creek" form has only been collected from a single location close t...
