Skunk Cory; C020
March 13th, 2012 — 1:19pm
This species is among the more popular Corydoras in the aquarium hobby and is widely available. It may also be referred to as ‘arched cory’.
There exist a number of similar-looking congeners, particularly C. urucu (Britto et al., 2009), described from the rio Urucu in Coari municipality, Amazonas state, Brazil, and C. narcissus from the rio Purus. The latter appears to have also been traded as C. sp. ‘super arcuatus longnose’ while a larg…

Bronze Cory
March 13th, 2012 — 1:19pm
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…

Oscar
March 13th, 2012 — 1:19pm
This species is also referred to as ‘velvet cichlid’, ‘red oscar’, ‘tiger oscar’, or ‘marble cichlid’.
It is a popular aquarium fish although its adult size and typical life-span of 10-20 years must be taken into account before purchase. Numerous ornamental strains are now available, and while care is more-or-less identical for all of them a degree of additional care must be taken with the ‘long-finned’ variety which is a little less competitive than other forms.

Zebra Shovelnose
March 13th, 2012 — 1:19pm
This species is sometimes confused with B. juruense, especially when juvenile, but can be told apart quite easily by it’s more well-defined colour pattern, relatively slender body shape and longer barbels. It was described in the genus Meredontotus, but is currently included in Brachyplatystoma based on a pair of synapomorphies shared by memb…

Spotted Headstander
March 13th, 2012 — 1:19pm
Omnivorous and will accept most foods offered, with the stomach contents of wild specimens varying on a seasonal basis but mostly comprising insects and insect larvae (orders Trichoptera, Hemiptera, Homoptera) plus some terrestrial fruits and even scales of other fishes (Sánchez et al., 2003).
In the aquarium offer live Daphnia, Artemia, Moina, bloodowrm, etc., vegetable matter in the form of blanched spinach, lettuce, cucumber, fruit, algae wafers, etc., and good quality, sinking dried foods.

Marbled Headstander, Brachsensalmler (DE)
March 13th, 2012 — 1:19pm
Abramites spp. are separated from other anostomids primarily on the basis of their relatively deeper bodies and presence of a prominent, post-pelvic median keel, a feature unique to the genus.
At time of writing A. eques is the only other species recognised and is native to the Río Magdalena drainage in western Colombia.
It can be distinguished by possession of 13-14 bra…

Demon Eartheater
March 13th, 2012 — 1:19pm
S. jurupari is also known as ‘demon fish’, ‘jurupari earth eater’, ‘green horse face’, or simply ‘jurupari’ in the aquarium hobby.
It can be distinguished from other members of the genus by the following combination of characters: presence of a relatively small dark ocellus on the upper caudal-fin base; absence of well-defined dark blot…

Green Swordtail
March 13th, 2012 — 1:18pm
Wild swordtails are a fairly basic green colur. However the vast majority of swordtails available in the hobby today are hybrids of X.helleri with X.maculatus or X.variatus. There are a huge number of selectively-bred varieties available, including wagtail, lyretail, tuxedo, albino, neon, red, green and hi-fin.
Swordtails may undergo what appears to be a change in sex. In young fish this may simply be late development. However some adult females develop male characteristics which is thought …

The genus Apistogramma is among the most speciose of South American cichlid genera with around 70 species valid at present but many more awaiting description. In addition many species exist in two or more geographical colour forms which may or may not turn out to be distinct in the future. Hobbyists tend to label these with collection data if available in order to avoid mixing them and the potential of hybridisation.
Member species have also been organised into a series of species lineages, complexes and groups by authors in order to better separate them.

Cockatoo Cichlid
March 13th, 2012 — 1:18pm
Numerous ornamental forms of this species have been selectively line-bred for the aquarium trade, vernacular names for which include "sunset", "sunburst", "double red", "triple red", "gold", "white gold", "orange flash" and "albino". It has also been assigned the 'A' number A200 under the DATZ system with possibly conspecific, related forms similarly numbered A201, A202 and A203 depending on locality.
