Corydoras zygatus EIGENMANN & ALLEN, 1942

Black Band Cory

March 13th, 2012 — 1:20pm

Known from the Ucayali (río Samiria), Huallaga, Santiago, and Pastaza (ríos Bobonaza and Pindo) river systems in eastern Ecuador and northern Peru. These are all tributary drainages within the middle Río Marañón watershed, a major affluent of the upper Amazon river basin.

Type locality is ‘Río Hallagua system, Yurimaguas…

Corydoras rabauti LA MONTE, 1941

Rusty Cory

March 13th, 2012 — 1:19pm

The broad dark stripe in the dorsal portion of the body extends into the ventral portion on the caudal peduncle, and this character can be used to distinguish it from the very similar-looking C. zygatus, with which it is often confused. In C. zygatus the dark stripe does not extend ventrally on the caudal peduncle and is present only on the dorsal part.

Corydoras metae EIGENMANN, 1914

Bandit Cory

March 13th, 2012 — 1:19pm

Endemic to the Río Meta, a major tributary of the Río Orinoco in eastern Colombia and western Venezuela. It is known from several tributaries within the upper basin including the ríos Humea, Ocoa, Guatiquía (including its two branches the ríos Negrito and Guayuriba), Manacacias, and Metica (the name given to the upper Río Meta above its confluence with the Río Humea). It appears to be absent from the lower Meta and has not been recorded in Venezuela.

Corydoras melini LÖNNBERG & RENDAHL, 1930

False Bandit Cory

March 13th, 2012 — 1:19pm

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.

Corydoras leucomelas EIGENMANN & ALLEN, 1942

Blackfin Cory

March 13th, 2012 — 1:19pm

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…

Corydoras julii STEINDACHNER, 1906

Julii Cory

March 13th, 2012 — 1:19pm

Native to coastal river systems south of the Amazon delta in the states of Piauí, Maranhão, Pará, and Amapá, northeastern Brazil. It has been recorded from the rios Guamá (including tributaries such as the rio Ararandeua), Maracanã (rio Peixe-Boi), Morcego, Parnaíba, Piriá, Caeté, Turiaçu (rio Jamari), and Mearim (rio Pindaré).

Reports from French Guiana and western Brazil appear to represent cases of misidentification.

Corydoras imitator NIJSSEN & ISBRÜCKER, 1983

Imitator Cory

March 13th, 2012 — 1:19pm

Endemic to the upper rio Negro basin in Amazonas state, northern Brazil, and Amazonas state, southern Venezuela. One specific locality is Igarapé Muiá (00°09’03″N 66°48’10″W).

Type locality is ‘Upper Rio Negro, eastern Amazonas, Brazil’, which is thought to refer to forest brooks crossing the “new army road”, north of São Gabriel da Cachoeira municipality.

Synodontis decorus BOULENGER, 1899

Clown Synodontis

March 13th, 2012 — 1:19pm

Also known as both the Clown Squeaker and Decorated Synodontis, the first ray of theis greatly extended in this species. It is one of the more secretive, nocturnal Synos and if you wish to observe it regularly we recommend the addition of a 'moon' light or a red bulb timed to come on for a couple of hours after the main tank lights go off. If some food is added to the tank under these lighting conditions it should emerge to feed.

This is one of only 3 members of the genus to exhibit…

Corydoras hastatus EIGENMANN & EIGENMANN, 1888

Tail-spot Pygmy Cory

March 13th, 2012 — 1:19pm

It exhibits slightly different behaviour to the majority of congeners in that it tends to swim in midwater and spends a large proportion of its time away from the substrate. Its morphology exhibits corresponding adaptations towards a pelagic existence with a relatively large eye, a more terminal mouth position, more strongly-forked caudal-fin, and more symmetrical body shape than most other Corydoras species.

Corydoras fowleri BÖHLKE, 1950

Fowler's Cory

March 13th, 2012 — 1:19pm

In addition, the colour pattern in aquarium fish traded or identified as C. fowleri is highly variable, but it is unclear whether such differences represent diversity within or between populations. Nevertheless, colour pattern is typically used to distinguish them, with fish from Peru possessing a greater extent of dark pigmentation on the body generally referred to…
