Corydoras eques STEINDACHNER, 1876

May 10th, 2014 — 3:49pm

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.

Corydoras cochui MYERS & WEITZMAN, 1954

Barredtail Cory, C022

February 23rd, 2014 — 6:55pm

This small species can be told apart from the similar-looking congener C. habrosus by possession of 4-5 (vs. 2-3) dark markings along the side of the body.

Aspidoras taurus LIMA & BRITTO, 2001

February 8th, 2014 — 1:27pm

A. taurus can be told apart from congeners by the following combination of characters: infraorbitals and preopercle covered by thick skin and not visible externally (vs. covered by thin skin and externally visible in other Aspidoras); nuchal plate reduced, covered by thick skin and not visible externally (vs. well developed, covered by thin skin and visible externally); lateral line absent posterior to two small lateral line ossicles (vs. lateral line present on at least first body plate).

Aspidoras spilotus NIJSSEN & ISBRÜCKER, 1976

C125

February 8th, 2014 — 1:00pm

Aspidoras spp. are foraging omnivores and will accept most sinking dried foods, as well as small live and frozen varieties such as chironomid larvae (bloodworm), Tubifex, etc.

Feeding a varied diet will ensure the fish are in optimum condition.

Corydoras sp.

C115, C116

June 27th, 2013 — 8:10pm

This unidentified species was originally traded under the C-numbers C115 and C116 but these two are now thought to represent the same species, while fish collected from Manú National Park and sold as C. sp. ‘Manu 1 long nose’, C. sp. ‘Manu 4’, C. sp. ‘Manu 7’, and C. sp. ‘Manu 8’ may represent this species as well.

It’s highly variable in terms of colour patter…

Corydoras splendens (CASTELNAU, 1855)

Emerald 'Brochis'

June 18th, 2013 — 10:57pm

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…

Corydoras britskii (NIJSSEN & ISBRÜCKER, 1983)

Giant Brochis

June 18th, 2013 — 10:37pm

Brochis was first synonymised with Corydoras by Britto (2003), since the latter genus cannot be considered monophyletic if the former is accepted as valid. This decision has been supported in subsequent phylogenetic studies by Shimabukuro-Dias et al. (2004) and Alexandrou et al. (2011), although the name Brochis is still common in aquarium literature. It is likely that the genus will be revalidated and expanded in the future following a required taxonomic review of the subfamily Corydoradinae as suggested by Alexandrou and Taylor (2011).

Corydoras multiradiatus (ORCÉS V., 1960)

Hognose 'Brochis'

June 18th, 2013 — 9:27pm

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 carlae NIJSSEN & ISBRÜCKER , 1983

February 6th, 2013 — 4:53pm

This species is not available on a commercial basis but was collected and introduced to the aquarium hobby by Hans Georg-Evers in 2010.

It’s similar in appearance to a number of congeners including C. diphyes, C. erhardti, C. garbei, C. paleatus and C. steindachneri but can be told apart from most of them by possession of two large, indistinct, dark blotches in the middle of each flank.

Corydoras boesemani NIJSSEN & ISBRÜCKER, 1967

Boeseman's Catfish

February 5th, 2013 — 10:06am

This species appears endemic to and abundant within the upper Suriname River system, Suriname.

Type locality is given as ‘little tributaries of Gran Rio between Ligolio and Awaradam Falls’, this corresponding to a section of the Suriname River, which is known as ‘Gran Río’ in parts of its upper basin, upstream of Brokopondo reservoir and not…
