There are a dozen described species of Microsynodontis but most are not seen in the hobby. This species is one of the commoner ones however. Microsynodontis are much smaller than Synodontis species, with M. batesii being the largest. They can be distinguished from Synos and the similar Mochokiella by the rounded or slightly forked caudal fin. The is highly forked in the other genera. Interestingly in Microsynodontis the eyeball is fixed and cannot be moved unlike in Synodontis which has a moveab...

A rather rare fish in the UK hobby. It occasionally shows up as a contaminant among imports of more popular species. The taxonomic status of all species in the genus Moenkhausia is currently Incertae Sedis, meaning uncertain. The genus is currently used as something of a catch-all for a large number of small characin species. Most experts agree that a full revision is required, with the likely outcome that many of these will be placed into new or different genera....

All Mystacoleucus species possess a procumbent predorsal spine orientated towards the head, though it can be difficult to spot with the naked eye. This can become entangled in an aquarium net so care must be taken when handling the fish. The trait is shared by members of Tor, Spinibarbus and Paraspinibarbus although there exists no strong evidence to suggest that these genera form a monophyletic lineage and it is...

Nannacara Anomala are widely available in the trade, and are generally regarded as an excellent beginner's fish. If a beginner is interested in keeping Cichlids and learning about breeding, then these fish are absolutely ideal. Anomala are attractive, hardy and usually quite cheap to purchase. Like some species of the Apistogramma genus, the mother may use fascinating body language to communicate with her fry when she is caring for them. If there is more than one male in a tank smalle...

This species has been referred to the genera Poecilobrycon and Nannobrycon in the past and in the aquarium hobby is also known as 'rocket', 'brown', 'brown-tailed', 'diptail', or 'tubemouth' pencilfish.It's a popular aquarium fish and has an interesting oblique swimming-style, a behavioural trait shared only with N. unifasciatus among congeners. In the original description the colour pattern is given by Steindachner as a brown lateral stripe exte...

Inhabits sluggish blackwater tributaries, small rivers and swampy areas, particularly in areas with dense growth of aquatic or overhanging riparian vegetation, submerged woody structures and leaf litter. The water is typically stained darkly with humic acids and other chemicals released by decaying organic material, the dissolved mineral content is generally negligible and pH can be as low as 4.0. N. minimus occurs sympat...

This species has been referred to the genera Poecilobrycon and Nannobrycon in the past and in the aquarium hobby is also known as 'oneline' or 'red fin' pencilfish. It's a popular aquarium fish and has an interesting oblique swimming-style, a behavioural trait shared only with N. eques among congeners. The most recent diagnosis of the species appears to be that giv...

We're unsure if this species has ever been traded on a commercial basis though we know of several private collectors who've maintained it. It's difficult to confuse with any other balitorid due to the small adult size and distinctive orange to reddish-brown body colouration, and was originally described as a subgenus by Herre (1944) before Silas (1953) raised it to full genus status. It was later syonymised with Homaloptera by Alfred (1969) but has been generally accepted as a distinct, valid genus since Roberts (1989).

Deservedly one of the most popular Tanganyikan species available in the hobby, N. brichardi is ideal for newcomers to both Rift Lake cichlids and cichlids in general, being beautiful and easy to keep and breed. It is seen for sale under several common names including "Fairy Cichlid", "Lyretail Cichlid" and "Princess of Burundi". There are several colour morphs available, although these do not vary much in patterning, and an albino form is also occasionally available...

Several geographical morphs of this species are available, including "Sambia" and "Kipili". These vary in base colour from blue to yellow to white. It is not recommended for the general Tanganyikan community due to its aggressive and predatory nature....

It can be distinguished from the similar N. sexfasciatus by the presence of only five, rather than six, vertical bars on it's flanks. It is not recommended for the general Tanganyikan community due to it's aggressive nature, particularly when breeding....

Not a fish for the general Malawi cichlid community, N. livingstonii is an ambush predator in nature, often being seen hanging motionless around rocky structures, in Vallisneria thickets or on the floor of the lake. It is a sedentary species and does not move around a lot. This is a behavioural adaptation known as thanatosis, or 'playing dead'. This strategy is usually used as for defensive means in other animals but in N. livingstonii is adapted for offensive means. The fish has a mot...

Not a fish for the general Malawi cichlid community, N. venustus is an ambush predator in nature. It is often found hanging motionless around rocky structures, in Vallisneria thickets or on the floor of the lake. It is a sedentary species and does not move around a lot. This is a behavioural adaptation known as thanatosis, or 'playing dead'. This strategy is usually used as for defensive means in other animals but in N. venstus is adapted for offensive means. The fish has a mottled col...

One of the largest goby species in the world, O. marmoratus is unsuitable for the vast majority of aquaria, but is an interesting oddball for the true enthusiast with the facilities to house it properly. It is a nocturnal ambush predator and generally remains motionless during daylight hours unless striking at food. It is a popular food fish in some of its native countries, where it is known as soon hock....

Some Sumatran and Bornean populations of the highly variable P. shelfordii superficially resemble P. piperata which can cause issues with identification as the two often occur together. In general however the body patterning in P. piperata is than that of P. shelfordii and they differ in vertebral counts (mode 47 vs. 50, respectively).

P. fasciata is rarely seen in the trade and is typically available only as bycatch among shipments of Sinibotia spp., particularly S. robusta. According to current classification numerous species from several genera are considered synonymous with it.

This species is still considered a member of the genus Nemacheilus by some sources, but it was reclassified and placed in Acanthocobitis by Grant (2008). Acanthocobitis sinuata, generally considered a junior synonym of A. mooreh (Kottelat, 2012b), also appears distinct and differs in geographical distribution plus number of dorsal-fin rays (2-3/9-10 in A. mooreh vs. 2/8-9 in A. sinuata) and some aspects of colour pattern.

This occasional import is sometimes offered for sale as P. ranga, the Indian glass fish. Unlike that species however, P. siamensis is an exclusively freshwater fish and should never be kept under brackish conditions. It can be distinguished from ranga by the lack of patterning behind the eye and it's generally more elongate body....

This species is not generally available in the aquarium hobby on a commercial basis but is occasionally collected and distributed by private aquarists. It's name is sometimes misapplied to commercial shipments of other species, and there also exist a number of other fish with rounded caudal-fins that may or may not be conspecific, including P. sp. 'blue line' and P. sp. 'Selatan' from Sumatra.

Generally considered one of the hardiest small cyprinids available in the aquarium hobby, P. conchonius is an excellent choice for the beginner. Selective breeding has produced various ornamental strains including long-finned, 'veil-tail', 'super red', 'neon', and 'golden' forms. It's also been hybridised with some congeners although the offspring of such experiments are apparently infertile. It was formerly included in th...
