Endemic to the Rakhine Yoma/Arakan mountains in Rakhine state, western Myanmar; this range forms a natural barrier which cuts the state off from the remainder of the country. It was originally collected from a handful of streams and rivers of the western, interior, slopes of which the type specimens originated from the Kananmae Chaung, a coastal rivulet draining into the Bay of Bengal (Kullander and Fa...

B. rosea is a relatively recent addition to the aquarium trade but has proved very popular since it's colourful, hardy and usually quite cheap making it ideal for beginners. It's sometimes sold as 'purple passion danio'. It's very similar to B. albolineata sensu stricto but differs in several characters, notably the relatively slimmer body, shorter rostral barbels and lack of...

Adult size is comparable to B. nigrofasciata, and in the description paper the authors hypothesise that the two are closely-related given they share other features such as similar barbel length (plus some additional merisitic counts), absent lateral line and spotted pelvic fins. The two are easy to tell apart, however, since in B. tinwini the P+1 stripe is composed of a series of spots (vs. solid), it possesses an indistinct P+2 str...

This species can be told apart from the very similar-looking congener B. filamentosum by its smaller adult size (B. filamentosum can grow to almost 3 m in length), shorter maxillary barbels (never extending beyond base of adipose fin (vs. extending beyond base of adipose fin), moderately-forked with lobes of equal size (vs. deeply-forked caudal fin with upper lobe usually longer than the lower) and body col...

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...

Several Brachyrhamdia species have developed colour patterns that mimic syntopically-occurring Corydoras spp. throughout the life-cycle, and the remainder, including B. meesi, may mimic Otocinclus or smaller Corydoras spp. when juvenile. They're easily told apart from Corydoras by their significantly longer barbels and lack of scute-like plates on the body.

This species is relatively uncommon in the aquarium hobby but is available on occasion, sometimes mixed in among shipments of the congener C. salivator. These two can be told apart by the fact that C. salivator possesses a series of distinct dark bars on the head and body in both sexes, a colour pattern unique within the genus. It is also similar t...

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...

C. carsevennensis has formerly been synonymised with C. arnoldi but was considered separate by Zarske (2011) using the following combination characters: absence (vs. presence) of a silvery-white to white patch in the centre of some of the flank scales in males, particularly in the lower half of the body; absence (vs. presence) of a horizontal dark body bar in nuptial males; absence (vs. presence) of thin black margins in the dorsal, ventral and anal fins; eggs deposited among submerged vegetation (vs. eg...

This species is among a number of congeners native to the rio Negro region to possess a colour pattern with an oblique dark bar running along the dorsal surface of the body. This unofficial group also includes C. burgessi, C. davidsandsi, C. duplicareus, C. imitator, C. melini, and C. serratus, and among these C. duplicareus is most easily-confused with C. adolfoi.

The majority of records derive from the Río Apure watershed in southwestern Venezuela, where C. habrosus has been collected in the states of Portuguesa, Cojedes, Barinas, Guárico, and Apure. Its distribution in Colombia is less clear but it is known with certainty from the Río Arauca and Río Casanare, the latter a tributary of the lower Río Meta, and it makes sense that it should also be found in other left bank Orinoco affluents between the Meta and Apure, which include the ríos Cinaruco and Capanaparo.

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'.

Given its wide natural range it seems logical that this species is or has been available in the aquarium trade, although its correct name may never have been applied. It is told apart from congeners by the following combination of characters: two pairs of barbels; a continuous midlateral stripe from the tip of the snout to the base of the caudal-fin, with a conspicuous small blotch at the posterior extremity, faintly marked on the caudal-fin; a faint mark between the anus and the anal-fin origin in juveniles; a narrow mouth.

C. hujeta is traded under various names including 'slant-nosed gar', 'hujeta gar', 'rocket gar' and 'freshwater barracuda' but it and other members of the family Ctenoluciidae have traditionally been referred to as 'pike characids'. They're all predatory fishes native to South America, included in the order Characiformes and currently spread across two genera; Ctenolucius with two species and Boulengerella with five. The two genera are ...

As with others in the genus little has been written regarding captive care of this species, but it makes a peaceful and unusual addition to larger aquaria. The best way of obtaining it may be to keep an eye on shipments of wild fishes from Indochina. It can be distinguished from congeners by possessing 20 circumpeduncular scales and lacking barbels entirely.

C. afra is easily confused with some species of Pseudotropheus, but can be distinguished by its smaller adult size and unicuspid (as opposed to bicuspid) teeth. Also in this species the black bars on the flanks continue into the dorsal fin, unlike in Pseudotropheus zebra, for example. It exists in many different colour forms in nature. These forms should not be mixed in aquaria as they may spawn with each other, producing unwanted hybrid fry. Despite this ability to interbreed, it's probabl...

This species is among the more well-known badids in the aquarium hobby, and is a popular choice for 'nano' aquaria since it is among the smallest percoid fishes known. It is easily told apart from congeners since it is the only species in which males possess a series of seven iridescent blue vertical bars on the flanks.

This species is one of three similar-looking members of the genus alongside D. johorensis and D. trifasciatus, while it may also be confused with Striuntius lineatus. Juveniles of all except S. lineatus exhibit a vertically-barred rather than laterally-striped colour pattern, the metamorphosis to adult patterning beginning at around 20 mm SL and normally being complete by 30-40 mm.

This species is poorly known and first appeared in the hobby during 2005 but has rarely been seen since, probably because its natural waters lie outside the range of most commercial collectors. It can be distinguished by a combination of characters including: lateral line complete; infraorbital process absent; two pairs of short barbels; 8-9 branched dorsal fin rays; 12-13 branched anal fin rays; P stripe originating above pelvic fin and extending to en...
