Corydoras kanei GRANT, 1998

C026, C046

December 11th, 2014 — 3:42pm

Prior to description C. kanei was assigned the ‘C’ numbers C026 and C046.

Among congeners it is most easily-confused with, and sometimes traded as, C. atropersonatus, but can be identified by presence (vs. absence in C. atropersonatus) of dark markings in the anal and caudal fins, presence of numerous, smaller (vs. fewer, larger) dark spots on the body, and an overall darker (vs. paler) base colouration.

Corydoras gracilis NIJSSEN & ISBRÜCKER, 1976

December 5th, 2014 — 7:48pm

It can be distinguished from the majority of other Corydoras species by its distinctive colour pattern, comprising a uniform, lightish base pigmentation with a dark arched stripe extending over the upper portion of each flank, from the tip of the snout to the caudal-fin base. This is shared with a few congeners, however, including C. arcuatus, C. narcissus, and C. urucu.

Ctenopharyngodon idella (VALENCIENNES, 1844)

Grass Carp

September 30th, 2014 — 12:57pm

Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market.

Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.

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.

Asterophysus batrachus KNER, 1858

Gulper Catfish

February 8th, 2014 — 2:49pm

An obligate predator by nature, but captive specimens readily accept strips of white fish, whole shrimp, earthworms, and similar once they are recognised as food.

Adult individuals are unlikely to require feeding on a daily basis with 1-2 meals per week sufficient.

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).
