Also known as the Orange Striped Squeaker, in our opinion this fish is one of the most attractively patterned Synos. S. flavitaeniata can vary considerably in patterning and colouration but is difficult to misidentify. This fish is more sensitive to deteriorating water quality than many Syno species so aquarium maintenance must be rigorous. When it was first imported 25 or so years ago it commanded an extortionate price but thankfully is affordable today. Its flexibility with regards to w...

One of the most stunning and sought after species of Synodontis and though the cost of ownership has dropped slightly, it still commands a high price. Its natural deep water habitat, limited range and solitary lifestyle make collection for the hobby difficult and so it is rarely seen for sale. It also appears that the areas of the lake in which it occurs are threatened with ecological disaster. In the aquarium S. granulosa is intelligent and can develop into a real character, with many speci...

An attractively patterned, infrequently imported Syno that deserves more popularity in the hobby. It is occasionally confused with S. schoutedeni, which it superficially resembles.

The reason we have recommended the use of non-Tanganyikan cichlid hosts above is because a successful captive spawning using Tanganyikan cichlid species has never been recorded! This may be due to an evolutionary process that has been observed in the lake, in which many cichlid species appear to have learned to avoid S. multipunctata when breeding. This is similar to the rejection of alien eggs by the host species in brood-parasatising birds. Because no species of brood parasatising catfish occu...

This is one of the most common Synos seen in dealers' tanks and is often incorrectly labelled "Upside-down catfish". The true upside-down catfish is S. nigriventris and S. nigrita inverts far less frequently than that species although it does often rest in this position. Moreover, S. nigrita grows far larger than S. nigriventris and it is a common sight to see several adult specimens in shops that have been returned by unsuspecting owners. S. nigrita is often confused with the...

One of the commonest Synos seen for sale, S. nigriventris is occasionally confused with S. contractus. However, on close inspection the species are easy to tell apart as S. nigriventris lacks the large head and mouth and larger eye of S. contractus. The scientific name nigriventris refers to the fact that the belly of this fish is darker than the dorsal area. This is a form of camouflage, making the fish harder to spot by predators above, such as predatory fish, birds etc. It is a basic re...

This is the only species of Synodontis found in Lake Malawi. There exists both large and small-spotted morphs, both of which are available in the trade.

Also known as the Domino Synodontis or the One-spot Squeaker, several regional variants of S. notata are known, some of which have 3, 6 or 12 spots and others none at all. Some of these are seen for sale under the invalid name S. ocellata. It is also often imported with similar species such as S. nummifer or S.congica. These are usually then all sold as notata. S. notata is more active during the day than many Syno species and therefore makes a good addition to aquariums with more boisterous...

S. ocellifer is often confused with other similar species of Synodontis but can be distinguished by the length of thewhich in this species is very long and runs from just past the base of the to just before the caudal fin. In recent years many alarming hybrids of this species have been appearing on the market and these should be avoided in our opinion. Besides being attractively marked this is one of the hardiest Synos available and is a good choice for the beginner....

One of our favourite Synos and highly recommended for any Tanganyikan community aquarium. The dwarf form can even be kept in a South American community.

S. pleurops is a very nocturnal species and unless the light in the aquarium is dim will rarely be seen. It is also very distinctive and is hard to confuse with other species. It has very large eyes and a downturned mouth, denoting its algae grazing habits. It will rarely venture into open water in the aquarium, preferring to hug the surface of pieces of driftwood, rocks and broad plant leaves. The colouration and patterning can vary considerably depending on type locality....

This species is superficially similar to S. petricola but the spots on its body are larger than in petricola and it has a longer head. It is rarely seen in the trade, though can occasionally be found mis-identified as S. angelicus, S. petricola or Synodontis sp.....

S. robbianus is often confused with the similar but larger S. nigrita. They can be distinguished by the brownish base colour of this species as opposed to the greyer patterning exhibited by S. nigrita. It is also similar to several other Syno species, especially when juvenile. A hardy, adaptable species ideal for the newcomer to Synodontis but not often seen for sale....

S. schall is regarded as the 'bad boy' of the genus in aquarium circles. It is randomly aggressive and not particularly attractive. It is often confused with other similar species of Synodontis such as S. budgetti or S. clarias but can be distinguished by the length of thewhich, in this species, is very long and runs from just past the base of the to just before the caudal fin. It is an important food fish in some of its native countries....

In our opinion, this is one of the most attractively marked Synos commonly available in the hobby. The colour and patterning can vary considerably and the vermiculated pattern seems to intensify with age in well kept fish. When taken into consideration with its moderate adult size, this is an ideal beginners's Syno. One point worth noting is that this species seems very susceptible to bloating. While the cause of this is unknown, we suggest that feeding of dried foods be kept to a minimum. ...

This is an uncommonly imported Syno that is nevertheless very attractive. It has distinctive serrated edges to the pectoral fins and will exhibit its strongest colouration over a light coloured substrate....

The genus Puntius is currently viewed as something of a catch-all for well over 100 species of small to mid-sized cyprinid. Most experts agree that a full revision is required with the likely outcome that many species will be placed into new or different genera since it is clearly polyphyletic. When describing the grouping in 1822 Hamilton identified the defining characteristics as: presence or absence o...

Taeniacara Candidi are the source of much discussion amongst dwarf cichlid keepers. They are a highly attractive species, but require very specific water parameters and as such are seen as a challenge amongst even experienced south american cichlid keepers. Candidi are renowned for not liking water changes - they will commonly get "moody" after a water change, and will sulk at the bottom of the tank for over a day in some cases. Try to keep new water at the same temperature as the C...

Something for the true oddball enthusiast, this bizarre looking goby has been imported at least once over the last few years. It's a mud-burrowing species that digs networks of sloping tunnels in the substrate in nature. Apparently each series of burrows has several openings, one of which has a mound outside. According to Itani and Uchino (2003), this mound suggests that the fish "actively process sediment". Even more odd is its appearance (see picture). It has greatly reduced eye...

Bitterlings (see 'Notes') exhibit an unusual spawning symbiosis in which the interlamellar spaces of the paired inner and outer gills of living unionid mussels are used as a spawning substrate. During the reproductive period females develop a long ovipositor which is used to deposit eggs through the mussel’s exhalant siphon. Males then move in to males release milt...
