The genus Danio contains only the type species, D. dangila, separated on the basis of its larger size and the shape of the caudal-fin, which in adults is only slightly emarginate or even truncate in shape, a feature it shares only with Tinca tinca (the common tench) among other cyprinids. The remaining species, of which B. rerio is thought to be the most ancient, are included in the revalidated genus Brachydanio Weber & de Beaufort, 1916.

This species is also traded as 'golden cobra snakehead' and is available in the aquarium trade on a regular basis. It can be distinguished from other Channa species by the following combination of characters: 51-54 lateral line scales; 45-47 dorsal-fin rays; 28-30 anal-fin rays; 8-12 cheek scales; 50-52 total verte...

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.

Cichlasoma Trimaculatus is a large colourful cichlid, if a little aggressive. It is believed to be one of the fish that was used to create the hybrid Flowerhorn cichlid. We prefer it in its natural state. As with most large cichlids they can be fairly messy eaters so ensure decent filtration is provided. It is recommended to use a spraybar to disperse the water returning to the tank as trimacs will not appreciate strong flow....

Known from the middle and upper Amazon river basins in Brazil, Peru, Ecuador and Colombia. Type locality is 'Amazon River at Obidos, Cudajas, and Tabatinga; Rio Negro, Brazil.' It apparently practises an interesting reproductive strategy in which the eggs are deposited in a shallow depression excavated from the substrate and guarded by the male.

This species has been widely referred to as the congener C. nattereri in aquarium literature both prior to and post-publication of its official description in 2006. The two can be told apart quite easily by the fact that C. nattereri possesses a dark lateral stripe while C. meinkeni does not. C. meinkeni can be distinguished from all congeners by the followi...

This species' name is commonly misapplied to a number of similar-looking fishes and it can be difficult to identify if collection locality is unknown. In addition, colour pattern is variable and it's not clear whether this occurs between, within, or both between and within populations. In the original description, Steindachner did note that the first three dorsal-fin rays are completely black while the remainder is whi...

C. brevirostris was described from an aquarium specimen apparently exported from the Río Orinoco drainage in Venezuela, and its wider distribution is somewhat vague, usually being given as the Orinoco system plus unnamed coastal rivers in Suriname. This represents a somewhat disjunct pattern of distribution and if correct the species is also likely to occur in Guyana.

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.

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...

There are 4 other species of cory that may be confused with C. ourastigma at first glance. These are C. guapore, C. caudimaculatus, C. similis and C. spectabilis. They can be distinguished quite easily upon close examination, however. C. guapore, whilst exhibiting similar patterning, has a completely different body shape to ourastigma, having a much more rounded overall appearance. It also tends to spend a lot of time away from the aquarium floor, unlike ourastigma. C. caudimaculatus also has a ...

Crenicichla albopunctata

The genus currently contains seven species of which H. macrolepidota and, to a lesser extent, H. dispar are the only ones seen with any regularity in the aquarium trade. As well as having the widest distribution H. macrolepidota is also the largest member of the group. All representatives can appear superficially similar at first glance, the exception being H. lopezi which is endemic to a single island in The Philippines and displays a unique lateral band-like marking on the flanks.

Widepread in eastern Asia between the Yangtze and Amur river basins, including China (mainland and islands of Taiwan and Hainan), Korea, Mongolia, Russia, and Japan. It probably been introduced to Vietnam and Laos, or records from these countries represent another species.

A rarely seen, although attractive member of the severum family. This species is occasionally offered for sale through specialist cichild or South American dealers.

This undescribed species is part of the Hypostomus cochliodon complex, all of which were previously included in the genus Cochliodon. This is now considered a synonym of Hypostomus. Members of this group can be distinguished from congeners by several differences in morphology, most notably the hump-backed profile of mature fish and spoon-shaped dentition. These features, along with the fishes tendency to eat wood, are shared with the Panaque genus of the Ancistrinae subfamily, but the two genera...

An attractive and very hardy larger plec.

Known from Great Lakes Erie and Michigan with distribution extending south through the Mississippi River basin to the Gulf of Mexico drainages where it's said to occur between the lower Apalachicola River in Florida and the Nueces River in Texas. It may also be found in the Rio Grande which forms the border between Mexico and the United States further south where records include Falcon International Reservoir, for example.

Still widely referred to as hoplosternum thoracatum the hoplo cat is a popular and hardy fish. These fish have the ability to breathe atmospheric air by gulping down mouthfuls of air and the oxygen is then absorbed into the bloodstream through the intestine. This allows the fish to endure poor conditions in the wild but it can still be observed exhibiting this behaviour in captivity. The hoplo is also eaten as a food fish in parts of South America....
