Goliath Tigerfish

The Goliath Tigerfish, Hydrocynus goliath, is a ferocious predatory fish native to the Congo River Basin in Africa. It can grow up to 1.5 meters long and has be known to prey on small crocodiles and tearing large catfish into pieces! It occasionally attacks human since it is able to sense low frequency vibration in the water. It prefers to hunt in fast flowing water where smaller fish struggle to swim. Its massive teeth perfectly slide into distinct patches along its jaw. The Goliath Tigerfish is very rarely kept in any sort of aquarium although I did manage to spot a few at the Singapore River Safari the other day! See video below 🙂

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.
