Pictus Catfish

The Pictus Catfish, Pimelodus Pictus, is a small species of catfish with extreme long barbels. The barbels can even reach to the caudal fin! Pictus Catfish are active bottom feeders that are usually most active at night. They inhabit the Amazon and Orinoco river basins and are common in the aquarium trade. In captivity they are omnivorous and eat vegetables, blood worms and insects among others. They are relatively peaceful fish and can be kept with other fish of similar size. Larger Pictus Catfish, however, will have a go at smaller fish (small tetra’s for example). Pictus Catfish are non-territorial so a shoal of 5 or more will make this species of catfish feel more at home. Furthermore, it is important to provide plenty of plants, rock, caves and driftwood in soft water. A dimly lit aquarium encourages the fish to be more active.

Uara Cichlid

The Uara Cichlid, uaru amphiacanthoides, is a large species of cichlid native to South America in Northern Brazil and parts of Guyana that can grown up to 30 centimeters in length. It inhabits clear water tributaries, particularly around submerged branches and tree roots. Uara Cichlids can be recognized by their large eyes and distinguishing large spot on the body. In the aquarium it is a surprisingly peaceful fish considering its size and the aggressive behavior of most other cichlid species. It can be housed together with tetras, angels and species of characins. Uara Cichlids do need be housed in large tanks of about two meters in length. These fish can be fed frozen foods such as blood worms or brine shrimp, but will also happily eat vegetables such as lettuce, peas and spinach. Dried foods will also be gladly accepted. Juveniles often feed on the slime coat of their parents, similar to what Discus do.

Blackline Penguinfish

The Blackline Penguinfish, Thayeria boehlkei, also known as the hockey-stick tetra is a species of tetra native to the upper Amazon River basin in Peru and Araguaia River in Brazil. It has a distinguishing black line across its body which hooks downwards at its tail. It is highly recommended to cover the aquarium as these small fish have been seen jumping 2 meters out of the aquarium! Keep this fish in schools of at least 6 individuals (preferably more). The blackline penguinfish does not grow very large (max 7 centimeters long), so one does not need a very large aquarium to house a school of these fish. These fish are not too fussy concerning water parameters as long as the tank is cleaned periodically. This is a very peaceful fish excellent for a community tank. Goes well with other species of schooling tetra’s 🙂

Electric Eel

The Electric Eel, electrophorus electricus, is more closely related to catfish than to an eel. It originates from the Amazon and Orinoco river systems where there is plenty of mud and reeds for it to hide in. It is best known for stunning its prey by producing an electric shock up to 860 volt! The Electric Eel uses this electric shock to hunt its prey and it is very successful in doing so. The electric shock is not life threatening to humans as it is only a  quick discharge of electricity. However, it can still cause temporary numbing of a part of your body 😉

In the aquarium, the Electric Eel should only be kept by specialists as this species can easily grow up to two meters. It is not very active so an aquarium 2 to 3 times its body length should be enough. Important is to cover the aquarium as the Electric Eel can easily jump or force its way out. However, do let sufficient air through as the Electric Eel needs oxygen to survive. It will gulp for air every 10 minutes or so. Live or dead feeder fish and worms that are able to fit in its mouth will satisfy the Electric Eel’s dietary requirements.
