A large, robust, and uniquely patterned species, the Goldline Knifefish (Sternopygus macrurus) is found throughout the Pacific coastal drainage of Colombia and Ecuador, where it inhabits a wide variety of habitat types. These knifefish can be found in fast-moving freshwater streams as well as brackish water estuaries so they appear to tolerate a wide variety of water conditions. A large and outgoing species which will readily eat small fish, these knifefish are ideal for a species tank or a community aquarium consisting of large but relatively peaceful tankmates. Like most knifefish, they appreciate having ample hiding places but are not particularly shy.

A rare knifefish found in the deep water channels of the middle Amazon River in Peru and Brazil, the Pelican Knifefish is a distinctive species, with males of the species developing extremely elongated snouts which are assumed to be for interspecific competition for females, which have a more typical head shape for a knifefish. Little is known about their behavior in the wild, but they are likely an insectivore, using their highly developed ability to detect electrical current in order to locate food. In the aquarium, they are shy and best kept in a species tank or with other very peaceful fish. Due to their deep water habitat, very dim lighting, if any, is preferred, and they should be offered plenty of cover.

A unique and beautifully patterned knifefish, the Ossa or Trumpet Knifefish is a cryptic species often found hiding among leaf litter. Like most knifefish, they are primarily nocturnal, and use their long snouts to root for insect larvae and crustaceans to eat. In the aquarium, they are peaceful and somewhat shy, and best kept with other peaceful species. They will usually accept frozen bloodworms, brine shrimp, and other frozen foods, but are easily outcompeted for food by fast-moving or more aggressive eaters.

The bizarre White Tamandua Knifefish is widespread throughout the Amazon and its tributaries but is rarely encountered due to the depths it inhabits (18 – 30 feet). Its deep water habitat in the main river channels is almost entirely dark in most cases, and the fish exhibits a cave fish-like appearance because of this. Like most knifefish, it relies on its ability to sense electrical discharges to navigate and find food. In the aquarium, they are best kept in a specialized tank with few if any tankmates. They are slow to feed at first and may require live foods but will generally learn to take frozen over time. As a large growing, open water swimmer, they will require a very large aquarium built around meeting their unique care requirements.

One of the larger species of knifefish, the Clown Knife is found throughout much of Southeast Asia, where it is an important food fish. It is now extensively farm raised for food and for the aquarium trade. The Gold color form is a colorful line bred variety of the fish similar to an albino. A predatory species with a surprisingly large mouth, Clown Knives can easily eat fish up to 1/3rd their size in many cases. Despite their predatory nature, they are peaceful towards nearly all tankmates too big to be eaten.

A new and likely undescribed species of knifefish originating in Colombia’s Rio Caqueta, this species appears to be related to the Goldline Knifefish (Sternopygus macrurus). A large species which will readily eat small fish, these knifefish are ideal for a species tank or a community aquarium consisting of large but relatively peaceful tankmates. Like most knifefish, they appreciate having ample hiding places but are not particularly shy.

The Natterer’s Knifefish (Sternarchogiton nattereri) is extremely rare species of knifefish is found throughout much of the middle Amazon, where it inhabits mats of floating vegetation in low to moderate flow areas and feeds primarily on insect larvae. Adult males of the species develop a jaw full of huge, protruding teeth and were once thought to represent another genus and species entirely (Oedemognathus exodon). Males are thought to use these teeth in territorial disputes against other adult males, although the species is generally peaceful toward one another so long as they are provided with ample hides and cover.

An uncommon and beautifully marked species of knifefish, the Royal Clown Knife (Chitala blanci) is found in fast-moving waters of the middle Mekong along the Thailand – Laos border. A predatory species with a surprisingly large mouth, they can easily eat fish up to 1/3rd their size in many cases. Despite their predatory nature, they are peaceful towards nearly all tankmates too big to be eaten. Often shy at first, they will do best in an aquarium with ample hiding spaces and moderate to strong water movement. Over time, they will become more bold and active in the aquarium and larger specimens make impressive display fish with their vivid silver sheen, long undulating fin, and striking reticulated pattern of black markings which typically grows more intricate as the fish grows.

One of the more unique species of knifefish, the Aba Aba is found throughout much of Africa, where it inhabits shallow, slow moving bodies of water. While juvenile fish are often found in small groups, adults become solitary large predators which like most knifefish use a specialized organ to detect the weak electrical currents generated by other fish. In the aquarium, they tend to be extremely aggressive, often attacking tankmates at night. This combined with their huge adult size makes them best suited for a species tank.

This uncommon and beautifully marked knifefish is found in slow moving streams and lakes throughout much of Central and West Africa. The pattern can vary greatly depending on locale. It is fairly bold for a knifefish and can be aggressive toward some tankmates, so is best suited to an aquarium with similarly-sized fish. They will appreciate some cover in the form of driftwood or aquatic plants (live or artificial).
**Animals left in stock are heavily discounted due to low patterning.
