Catoprion mento

The Catoprion mentoa is widespread in water bodies of Brazil, Bolivia, Venezuela, Guyana and Colombia. The fish inhabit streams, rivers, and their tributaries densely overgrown with aquatic vegetation. In open water, the fish are very rarely seen, as although they are predators, they can still be a welcome prey for larger predatory fish.

The body of the Catoprion mento is disk-shaped. A kind of business card of these fish is their lower jaw, which is decently advanced. In contrast to the female, the male has an elongated anal fin, due to which the fish got their name - pennant. The juveniles have a silvery colouration. As the fish matures, their coloration becomes darker and the belly becomes pale red. In the wild, the fish reach a length of 15 cm, while in aquariums they are slightly smaller.

The piranha leads a secretive lifestyle, and the aquarium should provide ample shelter in the form of snags, caves and large stones. The perimeter of the aquarium should be densely planted with aquarium plants. The substrate can be any, preferably dark-colored. Place bushes of floating plants on the water surface. In nature, these fish are found in the so-called "black water", where water is strongly stained with tannins, released during the decomposition of organics. Preferably mimic these conditions in the aquarium, for example, by placing pieces of peat in the filter element of the water.

Keep Piranhas in a large aquarium, each fish must have at least 125 liters of water. Do not keep other fish in the tank with the piranhas, because all of them, even large in size, will certainly be eaten. Furthermore, piranhas may only be kept together at a young age. As soon as the fish become adults to keep them separately, because they are very militant against each other. Especially aggressive females who are constantly attacking the males and very often beat them to death.

Water parameters: temperature 23-26° C, hardness dH 1-5°, pH 5,8-6,5. Requires filtration using an external canister-type filter, aeration and a weekly change of 1/3 of the aquarium water with fresh water.

In nature, the Catoprion mento feeds on various fish and invertebrates. Basically, they eat almost anything that moves. In aquariums, the piranha piranhas are fed with fish meat, shrimps and mussels. Do not feed the fish meat of animals and birds, as this is not a staple food for them in nature and is much less digestible.


Catoprion mento do not breed under aquarium conditions. Fish are supplied to the domestic trade zoos from their natural habitat.

Life expectancy Catoprion mento in aquarium conditions is about 10 years.
