When kept in aquariums, of course, they do not reach this size, but they are still very large – up to 60 cm in length, which requires a large space to keep. An aquarium with pacu should be a volume of at least 1000 liters. It is better to keep them in artificial ponds. Pacu lead a mostly peaceful life in the neighborhood with fish of suitable size and disposition and live up to 10 years.

Cichlasomes severum (Cichlasoma severum) are amazing fish. They are not only beautiful, but also have complex behavior. The most interesting is the mating season of the Severum. When there is a shortage of males, the females pair up with each other. One of them takes on the behavioral “duties” of the males, but unlike some other species of fish, the sex is not changed. Severum become sexually mature 2-3 years after birth, with a life span of 10-18 years.
The longest-living aquarium fish are man-bred goldfish (all varieties). With very good living conditions and a balanced diet these magnificent aquarium fish can live up to 30 years. However, the average lifespan of these fish – about 15-20 years, which is also a lot.

The longest-living among the popular aquarium fish are cichlids and fish of the carp family.
