This species has a similar patterning to C. sterbai, but lacks the orange pectoral spines of that species. It's rare in the hobby....

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...

This species can be identified from similar-looking congeners by possession of a pair of small rictal barbels. Its colour pattern can vary considerably depending on collection locality, with some forms having been misidentified as other species in the past. Those possessing a dark marking on the sides of the body are sometimes referred to as Corydoras sp. 'olga'.

This species is sometime referred to as 'Virginia's catfish', Corydoras sp. 'Sangama' or 'Zangama', and prior to description was misidentified as both Corydoras bicolor and C. delphax. Unfortunately additional diagnostic characters cannot be provided since we've been unable to obtain the type description, and little has been written about this species since it was published.

Endemic to a handful of natural springs in the Río Verde valley, San Luis Potosí state, Central Mexico. The valley is believed to have once been filled by a large lake and the relict springs are part of the elevated Río (river) Verde basin which later drains into the much larger Río Pánuco system. Much of the aquatic fauna found in the valley is endemic to the area but in many cases threatened by introduced species.

C. afra is easily confused with some species of Pseudotropheus, but can be distinguished by its smaller adult size and unicuspid (as opposed to bicuspid) teeth. Also in this species the black bars on the flanks continue into the dorsal fin, unlike in Pseudotropheus zebra, for example. It exists in many different colour forms in nature. These forms should not be mixed in aquaria as they may spawn with each other, producing unwanted hybrid fry. Despite this ability to interbreed, it's probabl...

The surrounding area is semi-arid and the Bolsón de Sandia was once a beautiful oasis with a number of springs, abundant vegetation and diverse wildlife but has dried up over the last twenty to thirty years due to indiscriminate water extraction for agriculture and other human uses. Three endemic species of Cyprinodon, namely C. veronicae, C. longidorsalis and C. ceciliae, have been described from separate springs within the system...

This species was referred to as Dario sp. ‘Jaintia Hills’ or D. sp. ‘Bangladesh’ prior to its description. Type locality is 'India, Meghalaya, Jaintia Hills, Seinphoh stream at Umolong, 7 km from Jowai town, 25°31’36’’N 92°08’27’’E, 1320 m asl', and in India it has not been found elsewhere to date.

Halfbeaks derive their common name from the elongated lower jaw shared by all species. The 'wrestling' moniker given to this particular species is due to the tendency of males to fight with each other, often locking jaws in the process. It is used as a fighting fish in some of its native countries, with wagers being placed on the outcome of fights between males. The two fish are placed in a small container for fighting purposes, as they will spar incessantly in such confined conditions...

This species has mostly been collected from small (1-2 metres wide, 20-40 cm deep), moderate-to-swiftly-flowing streams with clear water, substrates of sand, gravel and rocks and no aquatic vegetation. Marginal vegetation was present in some cases, offering a degree of shade, and sympatric species included an unidentified Schistura sp., S. vinciguerrae, Misgurnus anguillicaudatus, Garra qiaojiensis,...

This species has become more common in the trade in recent years, and makes an interesting addition to larger communities. It develops bright red fins as it matures. Some specimens develop a pink sheen on the underside. These variations may indicate different species, as there are several in the genus that superficially resemble D. affinis....

This species was available in the aquarium hobby for a number of years prior to publication of the official description and was generally referred to as A. sp. 'Namak' or A. sp. 'Namak River'. It can be distinguished from other members of the genus by the following combination of characters: 10–12 anal-fin rays; 28–32 lateral line scales, 10–13 caudal peduncle scales; 8–10 gill rakers; 12–19, commonly 1...

This species is not a common aquarium species but is occasionally available from specialist retailers or breeders. It was initially named Adinia multifasciata by Girard (1859) before later being redescribed as Fundulus xenicus (mispelled 'Fundnlus') by Jordan and Gilbert (1882). Body stout and trapezoidal in adults, body depth usually 2 to 3 times in standard length; scales large, fewer than 30 scales along midlateral scale row...
