Very rarely seen in the hobby, this species makes an interesting oddball addition to the Tanganyikan community tank. The species in the family Mastacembelidae are known as "spiny" eels because the dorsal rays are stiffened. Care must therefore be exercised when handling them to avoid injuries. Spiny eels also have no swim bladder, an adaptation to their benthic lifestyle.....

C. travancoricus is probably the smallest species of puffer, and is certainly one of the more diminutive fish regularly found in the trade. It's cute looks, amusing personality and fascinating swimming action make it a justifiably popular import, although it's all-too-often sold without the correct information needed for its long-term health and care. It's also known as the Malabar puffer, in reference to the area of southern India that contains much of the species' natural r...

This species is not actually a piranha in ichthyologic terms, being monotypic and therefore unique. It was so named due to its general resemblance to true piranha, and the fact that it is quite closely related to Pygocentrus species. Mento means "chin", referring to the protruding jaw of the fish. This jaw structure, along with the adapted teeth, is used in its natural feeding behaviour. It has been observed to swim at great speed into a selected target, biting hard as it collides w...

Chaca are unsuitable subjects for the general aquarist, but are relatively popular among lovers of oddball species. This species is very similar in appearance to the closely related C. chaca. However, it is somewhat darker and redder in colour than its relative, and lacks the hooklets that occur on the lips and body of chaca. It is a true master of disguise, and is also known as the angler catfish, due to it's ability to use its barbels as a kind of lure, using them to simulate the movement...

Chaca are unsuitable subjects for the general aquarist, but are quite popular among lovers of oddball species. This species is very similar in appearance to the closely related C. bankanensis. However, it's usually a bit lighter in colour than its relative and possesses small hooklets on the lower lip and body that are not present in bankanensis. It's a true master of disguise and is also known as the angler catfish, due to its ability to use its barbels as a kind of lure. These can be...

Also known popularly as the rubbernose plecs, Chaetostoma species are seen for sale quite often these days. This is one of the more commonly seen, and provided its needs are adequately met, is a very hardy little fish. There's a bit of mystery surrounding its true identity, hence the species name, and it's sometimes misidentified in shops. The true L187 is currently known as Chaetostoma pearsei, and is a white-spotted fish. When buying Loricariids such as this always check the fish ...

Also known as the trout cichlid, this species makes a great centrepiece to a well-chosen community of big Rift Lake cichlids. An adult male in top condition makes for a truly jaw dropping sight. It is only occasionally offered for sale, as it is difficult to collect, living a predominantly solitary lifestyle. As a result, it is much sought after by enthusiasts. It is sometimes confused with the other species in the genus, C. spilorhynchus, but can be distinguished by its more elongate shape. ...

This species is largely unsuitable for the home aquarium given its eventual size and natural behaviour, and we know of only a handful of private aquarists with the facilities required to house it long-term. It's currently illegal to import or own the species in the United States, United Kingdom and several other countries unless in possession of an official license.

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...

This species is also referred to as 'giant', 'great', 'cobra', or 'Indian' snakehead. Although currently-considered to be distributed throughout much of southern Asia it is widely-accepted to represent a complex of related species in need of additional research. A number of geographical variants exhibiting diffe...

This species' name has been widely misapplied in the aquarium trade and hobbyist literature, most often in reference to the Southeast Asian species C. ornata, but unlike its relative is in fact very rarely exported for ornamental purposes although its is fished and cultured for food in India. It can be told apart from C. ornata by possessing fe...

One of the largest cichla species. Due to their large size, Peacock Bass are only really recommended for the experienced fishkeeper that can house them adequately. That said, they are a hardy and robust species that will adapt to a variety of conditions. Peacock Bass are becoming much more available in the hobby and are often seen for sale as cute 2" babies, often tempting people into buying a fish they will not be able to care for in the long term. Peacock Bass are also fished as...

Salvin's Cichlid has a well deserved reputation for aggression, especially when breeding. They are regularly available in the trade and make an extremely colourful addition to any north/central American aggression tank. Take care when choosing tank mates, however. If only this species is kept in the tank, it will be quite shy until mature or until the natural domination order has been established. If a single fish of this species is kept alone, it will be extremely shy, usually choosing ...

Known as the tambaqui in its native countries, this is the second largest species of scaled fish found in the Amazon basin. This alone should tell you much of what you need to know about its suitability as an aquarium inhabitant. In reality, it's debatable as to whether the species should be considered an aquarium subject at all. While pacu rarely reach their maximum size in captivity, they're still easily capable of growing to a couple of feet in length. The myth that fish will only g...

This species is not well known and rarely traded for the aquarium hobby. Unfortunately diagnostic characters cannot be provided since we’ve been unable to obtain the type description, and little has been written about this species since it was published. It looks very similar to several congeners, particularly C. acrensis and C. cruziensis.

This species is popular in the aquarium hobby and unlike the majority of congeners tends to spend a fair amount of time away from the substrate, often forming groups in midwater. It has been placed in the unofficial 'C. elegans group', which contains a number of species exhibiting similarities in morphology and colour pattern, some of which remain unidentified in scientific terms.

This species occurs alongside a near-identical congener, C. condiscipulus in nature. In fact condiscipulus literally means 'schoolmate', as the species are often found shoaling together. The only external difference between the 2 seems to be the longer snout and wider distribution within the Rio Oyapock of condiscipulus....

The form from the Río Tigre, previously referred to as the subspecies C. p. orcesi (Weitzman & Nijssen, 1970) was raised to full species status as C. orcesi by Isbrücker (2001), but this decision does not appear to have been followed by all authorities some of which consider C. p. orcesi a synonym of C. pastazensis. The two species are relatively easy to tell apart by colour pattern; in C. pastazensis the dark vertical...

This species has a similar patterning to C. sterbai, but lacks the orange pectoral spines of that species. It's rare in the hobby....

This species can be identified from similar-looking congeners by possession of a pair of small rictal barbels. Its colour pattern can vary considerably depending on collection locality, with some forms having been misidentified as other species in the past. Those possessing a dark marking on the sides of the body are sometimes referred to as Corydoras sp. 'olga'.
