This undescribed species is also traded as C. sp. 'ndoboi' or 'ndobnoi', and despite its lack of official recognition it's the most commonly-encountered member of the genus in the aquarium trade at time of writing. It can be easily-distinguished from the congeners C. brichardi and C. popelini by its adult body patterning which comprises two or three series of irregular, dark, laterally-orientated blotches, the upper of which is often contained entirely within the dorsal ...

Also known as the trout cichlid, this species makes a great centrepiece to a well-chosen community of big Rift Lake cichlids. An adult male in top condition makes for a truly jaw dropping sight. It is only occasionally offered for sale, as it is difficult to collect, living a predominantly solitary lifestyle. As a result, it is much sought after by enthusiasts. It is sometimes confused with the other species in the genus, C. spilorhynchus, but can be distinguished by its more elongate shape. ...

This species is only occasionally offered for sale, as it is difficult to collect, living a predominantly solitary lifestyle. As a result, it is much sought after by enthusiasts. It may be confused with the other species in the genus, C. caerulus, but can be distinguished by its deeper body shape and very distinctive black markings on its snout. Champsochromis have widely spaced teeth compared to some other pelagic predatory cichlids found in Lake Malawi, such as Buccochromis species....

C. bleheri is a popular aquarium fish though it remains unclear whether collection for the ornamentaol trade is having a detrimental effect on wild populations (see 'Habitat'). It's one of several genus members to lack pelvic fins and can be further distinguished from other Channa species by the following combination of characters: sides of lower jaw with one large cycloid scale; lateral line complete with 46-50 scales; 14 pectoral-fin rays; 25 anal-fin rays; 4-11 irregular reddish orange markings on the caudal-fin

It's one of several genus members to lack pelvic fins and following Chaudhuri (1919) also has 51 lateral line scales, 38 dorsal-fin rays, 28 anal-fin rays, 12 caudal-fin rays, 15 predorsal scales, pectoral-fins with alternating dark and light bands, and white-tipped dorsal...

This fish belongs to a very distinctive genus of mochokid. There are almost 50 species of Chiloglanis described to science, but most are never imported and even the commoner species, such as this one, are seen only rarely. They are very difficult to identify down to species level, as many are very similar in looks. Some are strongly sexually dimorphic with the males having thickened or enlarged anal and caudal fins. Chiloglanis are also sometimes confused with the other 2 genera of African sucke...

This species is not collected for the aquarium trade at time of writing. In contrast to other members of the genus older juvenile and adult individuals lack dark markings on the body while the jaw is more pronounced.

This species is also referred to as 'South American puffer', 'SAP', 'Amazonian puffer', 'Peruvian puffer', or 'Brazilian puffer' in the ornamental trade. Within the genus Colomesus, C. asellus can be immediately identified by possessing a unique transverse row of dermal flaps across the chin which is absent in its congeners C. psittacus and C. tocantinensis.

Together with the recently erected genus Mchenga, Copadichromis species form an exclusive group of Malawian cichlids commonly referred to as "Utaka" (prounounced "ooh-taw-kuh"). They're specialised to a pelagic lifestyle, and can be found living in huge numbers throughout much of Lake Malawi. Some tend to remain in the proximity of underwater reefs or rocky shorelines, while others occur mainly in more featureless, sandy habitats. Here they face the oncoming current, us...

Despite the ubiquity of its name in aquarium literature, confusion surrounds its true identity. Given it's the only member of the genus occurring on the island, fish from Trinidad do presumably represent C. aeneus (see our image), but the classification of those from other localities appears far from certain. Today the species is accepted to occur throughout much of South America, and indeed similarly-patterned fish do occur across a large portion of the continent. Some of these, such as the gree...

Although described as a member of Corydoras this species was later moved into the genus Osteogaster by Cope (1894), but this was later synonymised with Corydoras by Gosline (1940). It is sometimes confused with C. venezuelanus, while two similar-looking, unidentified fishes from Peru have been assigned the codes CW007 and CW043, respectively.

In the aquarium hobby, the population from the rio Tiquié has been referred to as 'C084', while a similar, but larger, form from the Río Huallaga in Peru is known as 'C085'. Both forms have been marketed as C. sp. 'mega metae'. The existence of multiple, similarly-coloured species which coexist and sometimes form mixed schools is relatively common in the genus.

The genus is included in the family Callichthyidae, of which members are often referred to collectively as 'armoured' or 'mailed' catfishes group due to the presence of bony plates in place of scales on the body. Their taxonomy can be confusing, and numerous undescribed species are also thought to exist.

Corydoras are members of the armoured catfish family. The genus name means "helmet skin" and the fish live up to this name as they are rather tough little fish. They also have spines in the leading rays of the pectoral fins to deter larger predators from eating them. Corydoras are sometimes observed taking a gulp of air at the water surface: this is because they can absorb oxygen through their gut. It is not known why cories do this even on oxygen rich waters. Along with the bronze ...

It also exhibits morphological adaptations to an existence among rocks in a flowing environment, such as a cryptic colour pattern, reduced spine length in the dorsal and pectoral fins, ventrally-oriented pectoral fins, slightly emarginate caudal-fin, and reduced body depth. Reduced fin spines and body depth are typical features associated with the related genus Aspidoras, but the...

This species was formerly included in the genus Brochis alongside C. britskii and C. multiradiatus, and is sometimes referred to as 'common brochis'. Juveniles have a mottled colour pattern and are sometimes traded as 'hi-fin cory' due to their enlarged dorsal-fin. C. splendens can be told apart from other ex-Brochis species by possession of 10-12 dorsal-fin rays...
