One of the most common and popular Cichlid species in the hobby, the vast majority of Kribensis (often simply called "Krib" by many fishkeepers) seen in the hobby today are captive bred and are far more adaptable in terms of water chemistry than the wild fish. They also tend to be less aggressive when breeding. An aquarium sport albino form is available and is fairly popular. This fish is one of the best choices for newcomers to both Cichlids and fish breeding, being of a manageable...

This stunning species is now much more readily available than it once was. There are over a dozen morphs available, including "Dehane", "Moliwe", "Kienke", "Lobe", "Wouri", "Nigeria Red" and "Calabar". Males and females of these should not be cross bred in order to keep the lines pure. It can be distinguished from others in the genus by the more pronounced upper lip, which is often bright yellow in colour. Males of this spe...

Due to its highly amphibious nature this must be one of the most interesting, endearing species that can be kept in aquaria. Some specimens rarely enter deep water, preferring to sit in the shallows with the body submerged and eyes protruding above the surface. Others seem to favour resting completely exposed on rocks, sand or bogwood, returning to the water periodically to wet themselves. Subdominant individuals (those that are unable to secure a favourable territory) tend to attach themselves ...

This species was considered a colour form of the related Pethia cumingii prior to its description. It can be told apart from P. cumingii by the following combination of characters: maximum standard length 33.6 mm (vs. 41.2 mm); smaller eye diameter (9.8-10.5, vs. 10.8-12.1 % SL); 11+13 (vs. 11+15) vertebrae; cleithrum with a single spine (vs. smooth); proximal arm of fifth ceratobranchial with an oval...

P. interruptus are quite sensitive to water quality and if a high standard is not maintained the development of the males' fins may be impaired and the fish will lose colour. They are also quite an easily frightened fish, particularly if they are not maintained in numbers. This species is most often seen for sale as a fairly drab, greyish 1 1/2" fish and is often overlooked. However once they are settled into the aquarium and have begun to mature they develop spectacular colouration. ...

P. hystrix is sometimes sold as P. sp. "C", and is much sought after in the hobby. The species is usually recommended as a good beginners' ray due to its relatively small adult size. However due to current Brazilian legislation regarding the export of rays it's almost never available at present, and tends to command a high price when it is. The fish sold as hystrix in the trade are almost always Peruvian in origin and erroneously labelled. We've seen P. humerosa, P. yep...

P. leopoldi is aruably one of the most stunning freshwater species in the hobby and comes with a price tag to match. A fully grown one of these makes a jaw-dropping sight. Sadly exports from Brazil are now illegal under the IBAMA regulations, although captive bred fish are available occasionally. The price tends to be even more expensive as a result. A rare form in which the light spots appear as rings with black centres is known as P. leopoldi "eclipse" is more costly still. The stunn...

P. motoro is one of the most popular members of the genus with aquarists. Whilst it is quite easily obtainable and hardy once settled in, it does grow very large so make sure you can house it adequately long term. It should also be noted that the males of this species are among the most violent when in the mood for spawning and females can end up on the wrong end of a serious beating. If you're keeping a pair or group of these keep a close eye on proceedings and be prepared to separate them...

It appears that this species has not yet appeared in the western hobby, probably because commercial fish collections don't normally take place in its native waters although the goby Rhinogobius zhoui has been available occasionally. We're unable to provide details of distinguishing characters since no diagnostic key to the genus exists in English at time of writing, but based on the images available it does appear to possess reddish dorsal and caudal fins. The specimens pictured were i...

This species is also traded as 'forktail rainbowfish' or 'yellow forktail', and it's also undergone several changes in scientific name since description. Pseudomugil furcatus is the original designation, but Allen (1980) created the genus Popondetta for it on the basis of morphological characters including number of anal-fin rays (16-20 in P. furcatus, 8-12 in other Pseudomugil spp.), absence of anterior...

One of four similar-looking, laterally-striped 'Puntius' spp. native to Southeastern Asia alongside 'P.' gemellus, 'P.' johorensis, and 'P.' trifasciatus. Of these 'P.' lineatus is most often confused with 'P.' johorensis by virtue of the fact that these two seem most common in the aquarium trade. Telling them apart is relatively simple since 'P.' lineatus has 0 - 1 pairs of barbels (vs. 2 pairs in the other three species), juv...

Type locality is 'Mae Nam Huey Bon, kilometer 45 on road from Amphoe ThaWang Pha to Amphoe Chiang Kham, Chiang Rai Province, Thailand', and this species appears restricted to the Mekong and upper Chao Phraya river basins in northern Thailand and northern Laos. The specimens pictured here were collected from th...

The identity of this species was unclear for a number of decades prior to its redescription by Ng and Kottelat (2013). The confusion originated with Brittan (1954) who misidentified specimens of R. tornieri as R. dusonensis and was exacerbated by Alfred (1963) who concluded that the holotype of R. dusonensis was conspecific with R. myersi.

R. kalochroma exhibits variable patterning across its range according to locality with some forms possessing a line of spot-like markings connecting the two dark blotches on the flanks and others more intense body colouration. Juveniles are sometimes confused with Boraras maculatus and adults with the similarly-patterened R. elegans although the latter is easy to identify by its overall silver, as opposed to pinkish/reddish, colouration. The only congener for which it may be genuinely mistake...

It is unclear if this species has been available in the aquatic trade as collections from its native waters only occur sporadically, therefore we have based much of the information here on experience with its closest relative R. kalochroma. These two are almost identical in appearance and share some meristic features but R. kottelati possesses an additional, oval-shaped dark blotch on the caudal peduncle, lacks the stripe in the middle of the seen in R. kalochroma and is consequently easy to dis...

This species is also traded as 'Bornean redfin rasbora', 'sunshine rasbora' and 'dwarf volcano rasbora' and first appeared in the hobby during the latter part of 2010. It can be told apart from all other members of the genus by a combination of the following characters: possession of small tubercules on the dorsal surface, posterior to theand continuing onto the upper part of caudal fin, visible as an irregular 'crest' when a specimen is viewed laterally; ...

This species is rarely seen in the trade and little has been written regarding its captive care. It's possible that several colour forms may exist depending on collection locality. Rainboth's 'Fishes of the Cambodian Mekong' characterised members of Rasbora by possession of an unbranched, non-spiny firstray and seven soft dorsal rays, origin of thein the middle of the body, five branchedrays, a small mouth not extending below the eye and a lack of barbels. It's long b...

R. rubrodorsalis occurs sympatrically with the very similar-looking R. borapetensis over some of its natural range but is much the rarer of the two in the aquarium hobby. They are easily distinguishable from one another because R. rubrodorsalis has a bright red blotch in thewhilst in R. borapetensis the dorsal is colourless and only the base of the is coloured red. This species is sometimes sold under the erroneous name(s) R. beauforti or R. sp. cf. beauforti, probably because it was picture...

This popular species is also known as the 'three-lined' rasbora and provided a large enough tank is available it is an excellent choice for those new to the hobby. The 'scissortail' moniker is derived from the characteristic twitching motion of the when the fish is at rest. It can be distinguished from the similar R. caudimaculata by lacking red colouration in the and from R. spilocerca by its much larger size. Several geographical forms appear to exist as some wild populatio...
