An uncommon and large growing species of knifefish, the Bronze Featherback Knife (Notopterus notopterus) is found in slower moving waters and floodplains throughout Southeast Asia. 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.

The Dwarf Centipede or Pygmy Centipede Knifefish (Hypopygus cf. lepturus) is commonly found throughout the Orinoco and Amazon river basins. However, these were collected from the Nanay of Peru. They are a shy fish, but seem to adapt well to an aquarium with lots of cover, including leaf litter and woods with subdued lighting. When offering food, they will accept frozen baby brine shrimp and rotifers. A social species, they are best kept in groups in the aquarium.

The Glass Knifefish is one of many similar-looking species in the genus Eigenmannia native to the Orinoco and Rio Meta drainage in Colombia and Venezuela. Named for its partially transparent appearance, the Glass Knifefish is a fascinating aquarium resident which tends to be less shy than some of the more well known knifefish species. It is also typically found in large aggregations in the wild and will do best when kept in groups in the aquarium so long as there is ample space and hides in the form of driftwood or caves. Although it is a peaceful species and compatible with most tankmates, they are slow and sometimes finicky eaters so fast-moving or aggressive feeding species should not be kept with these unique fish.

They are nocturnal but will learn to come out when fed.

A longtime aquarium favorite, the Black Ghost Knifefish is a distinctive and unusual knifefish found throughout much of the Amazon and its major tributaries. A nocturnal and generally shy fish, like all knifefish they use a weak electrical discharge to sense their surroundings and find food. Although slow growing, they can reach the impressive size of 14″ or more and tend to prey on smaller fish as they grow. Black Ghost Knifefish are intelligent, often learning to eat from their owner’s hands or even to allow themselves to be “pet” once adapted to aquarium life. In the aquarium, they require plenty of cover, and may be outcompeted for food by more aggressive tankmates but are otherwise hardy and adaptable. This species is territorial, and generally best kept one per aquarium especially as adults.

The Brown Longtail Knifefish is likely an undescribed species very similar to the more commonly encountered Goldline Knifefish (Sternopygus macrurus). It originates from Eastern Colombia in the Meta drainage and could potentially be a regional variant of S. macrurus that lacks the distinctive gold line. Based on their body shape and genus this is likely to be a large and outgoing species that will readily eat small fish, making them suited 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 African Black Knifefish is a widespread, medium-growing species found in freshwater streams and swamps throughout much of West and Central Africa. Unlike many other knifefish species, it is a social fish that is typically found in schools and should be kept in groups in the aquarium. The African Black Knifefish is a peaceful species and will generally get along well with all tankmates too large to be prey. In the wild, they are found in a wide variety of habitat types but show a preference for slower-moving shallow waters with plenty of cover in the form of submerged branches or aquatic vegetation.

Blax’s Longtail Knifefish (also sometimes known as the Rat Tail Knifefish) is an active, large-growing species known from the Rio Tocantins and other lower Amazon tributaries in Brazil. In the aquarium, this is a relatively hardy knifefish but like most of their relatives will do best in somewhat soft water and require plenty of hiding places in the form of driftwood, plants or caves. As a fairly active swimmer, this knifefish should also be provided plenty of open swimming space. They will readily accept most frozen and prepared foods and while not typically aggressive towards tankmates they will likely prey on very small fish or invertebrates.

A smaller growing and attractively marked species of knifefish known from Colombia and Venezuela, the Blunt Nose Marbled Knifefish is similar in care to its more well-known relative, the Black Ghost Knife. Unlike many other knifefish, this species is social and will do well in groups. In the wild, they typically inhabit shallow, soft water in ares with plenty of cover in the form of driftwood, leaf litter, and aquatic vegetation and should be provided with plenty of hiding places in the aquarium. A somewhat shy eater that requires small food items (frozen bloodworms and mysis work well in the aquarium), tankmates should be chosen carefully so they don’t bully or outcompete these knifefish for food.

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).

A little known and rarely imported knifefish found in parts of the middle and Western Amazon and its tributaries, the Duck Head or Duckbill Knifefish is a medium, heavy-bodied species that displays strong sexual dimorphism. Adult males have an elongated snout with large jaws that give the species its common name while females retain a more typical knifefish head shape. This species is more territorial than some other knifefish, and males especially will fight if kept together in anything but the largest aquariums. Relatively hardy, they are not overly particular about water conditions and will readily accept most frozen foods.

A large growing and unique knifefish, the Elephant Nose Knifefish is, as the name implies, distinguished by its elongated trunk which it uses to root in substrate to find food. They feed on insect larvae and crustaceans in the wild, but in the aquarium will generally accept small frozen foods like bloodworms or brine. Like most knifefish, they are shy and should be provided with plenty of cover in the form of driftwood and leaf litter in the aquarium.

A strange elongated knifefish found through much of the middle Amazon, the Thermometer Knife is a sand dweller, spending much of its time buried in fine sand with just its head visible above the surface. They use their long, sensitive snouts and sensitivity to electrical impulses to find small prey items like worms, insect larvae, and crustaceans buried in the substrate. In the aquarium, they are hardy fish but can easily be outcompeted for food by faster or more aggressive tankmates so are best kept in a species tank or with other peaceful, slow moving species. Like all knifefish, they are primarily active at night but will occasionally emerge during the day to forage and explore. Although two species in the genus Gymnorhamphichthys are often referred to as “thermometer knife”, G. hypostomus is the more commonly seen species in the trade.

A peaceful and cryptic knifefish species, the Centipede or Sierra Knife is found throughout much of the Amazon basin where it is found in shallow water areas, usually among leaf litter. They feed on insect larvae and crustaceans in the wild but in the aquarium usually take to frozen foods very quickly. A social species, they are best kept in groups in the aquarium and should be provided with plenty of cover in the form of driftwood and leaf litter. This species is shy by nature and tends to feed at night or in dim lighting, so tankmates if any should be chosen carefully as they are easily outcompeted for food by fast moving fish or more aggressive eaters.

They are usually found in areas of slow water movement and in warm, acidic water. Although they can be territorial towards each other in the aquarium, it is possible to keep them in small groups as long as ample cover is provided.
