An incredibly hardy, long-lived fish which can survive for over 20 years in captivity. These fish develop real personality and can learn to recognise their owner. They are often sold as cute juveniles in aquatic shops with no information provided as to their adult size. The young have an attractive barred patterning which fades as the fish grow, which they do very quickly. A golden variety also exists in aquaria. O. goramy is cultured commercially for food on a large scale in several countrie...

This fish is spawned very infrequently in captivity but some reports have been made. Fish are sexually mature from 4" and a pair should be obtained by growing on a group of youngsters and allowing a pair to form naturally. Once this occurs the other fish will most likely be eliminated so it is wise to be vigilant in order to avoid uneccessary losses. Apparently courtship occurs in an open section of water surrounded by floating plant material. The courtship consists of the fish circling ...

Parachromis Managuense are your typical north/central American large predatory cichlid. They are extremely attractive, but a large aquarium is required. They are not difficult to look after, as long as filtration is up to standard. Choose tankmates carefully - if you are hoping to breed Managuense, house a breeding pair or grow 6 juveniles up until a pair is formed. One of the biggest problems with breeding Managuense is the fact that a single spawn from 12" parents can produce 3000 f...

At one locality in the Kalindhi drainage the water was clear, 1 m at its deepest point and flowing either side of a small check dam, below which the flow was stronger though still not particularly fast. The substrate was composed of rocks and cobbles with a thick layer of fine silt and sand above the dam. There were no aquatic plants but marginal grasses and shrubs were growing to the margins with some submerged roots protruding into the water.

Know as the pirapitinga in its native countries, this is the one of the 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 o...

P. henlei is one of the more sought after ray species in the hobby due to its striking colours and impressive adult size. A fully grown one of these makes a stunning sight. Sadly exports from Brazil are now illegal under the IBAMA regulations, although captive bred fish are available occasionally. The price tends to be very expensive as a result. The species exists in various colour forms, with either white or yellow spots and a background colour varying between black and dark brown. The patt...

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...

Euryhaline and mostly inhabits coastal floodplains where it's found in both fresh and brackish habitats, including tidal estuaries and salt marshes. It's particularly common in swamps, billabongs, and slow-moving streams where aquatic vegetation grows densely, but some populations have colonised upper sections of freshwater streams. Larger individuals may also move into main river channels. Tappin (2010) gives the following ranges of parameters based on those taken from various localities: temperature 27 - 38 °C, pH 5...

It's debatable as to whether this species should be considered an aquarium subject at all, given its eventual size. All too often juveniles are sold without adequate information regarding their long term care. These cats can and will attain something close to their maximum size in captivity, and will do so quite quickly. The myth that they will only grow to match the size of the tank they're kept in is just that - a myth. It's also worth noting that species such as this can live f...

This is an excellent beginner's species as it is relatively peaceful and easily bred. Despite being undescribed to science it is widely available in the hobby. It is sometimes sold as Gephyrochromis acei. Several colour forms are available, including "yellow tail acei" and "white tail acei". None of these should be kept together in aquaria to prevent hybridisation. In nature it feeds specifically on algae and other organisms growing on submerged wood, and is the only ...

This species is normally imported alongside a smaller-growing, near-identical congener currently listed as R. cf. nantaiensis with both traded as R. candidianus. They can be separated by snout length, which is noticeably longer in R. candidianus, and adult size with R. cf. nantaiensis reaching just 50-55 mm. R. candidianus can be distinguished from other congeners by a combination of cha...

This fish is normally imported alongside the congener R. candidianus and is actually the commoner of the two in the aquarium trade. It looks very similar to R. candidianus but does not grow as large and possesses a more rounded snout. Most specimens also have spot-like markings on the sides of the head which has led to them being identified as R. nantaiensis, but the fish do no...

The identity of this fish is unclear but it has been traded as S. sp. 'Laos redtail'. Schistura is the most species-rich genus among nemacheilid loaches with some 190 members and it continues to grow with over 100 having been described since 1990. It may repre...

This fish was collected for the aquarium trade during 2012 but its identity has not yet been established. Schistura is the most species-rich genus among nemacheilid loaches with some 190 members and it continues to grow with over 100 having be...

S. maculatus is one of the better choices for aquarists new to this group of fishes. It grows to a manageable size, is relatively hardy, attractive and usually quite inexpensive. It's sometimes referred to by the alternative vernacular names "gold piranha" or "golden mac" in the hobby. There are in excess of 30 described species of Serrasalmus many of which appear superficially similar and have confusing taxonomic histories. S. maculatus and S. spilopleura have often ...

The native name for this species is Caribito Parguasero. It's sometimes sold as the "green tiger piranha" in the trade and is usually highly coveted and expensive when available. A notoriously sensitive traveller, mortality rates are sadly quite high among imported fish. The lack of fully-grown specimens known to the hobby is also a worry, and would suggest that the majority are not being maintained correctly. This really is a species for the specialist with the resources necessar...

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...

This species is a near-exclusive inhabitant of the upper water column and appreciates surface cover in the form of floating or overhanging vegetation. Other décor is relatively unimportant but can consist of a sandy substrate with leaf litter plus some large driftwood branches and twisted roots. Plants which can grow rooted in sand can al...
