Severums can live alone or with a breeding partner in a larger tank. To keep a school of three to four fish, a tank of 125 gal (568 l) is required.
Other fish that can share a tank with this species include other South American cichlids, omnivorous catfish, plecos, and even tetras. The only thing that needs to be checked is that they are kept with fish that require similar water conditions. Severums can be considered a community fish.

The body of a severum looks laterally compressed with flowy anal and dorsal fins that have pointed ends. They have a mid-range body size. The original severum cichlid has an iridescent green body and the underpart is gold or yellow-colored.
In juvenile fish, eight pronounced black bands run vertically downwards. These bands gradually fade as a severum grows older.
For this reason, a cichlid is called a banded cichlid. This fish is said to have a seeming appearance as it appears as if they are always looking up. Many colored counterparts have been produced by breeding severum like the red severum, green severum, and gold severum.

Gold severums are one of the captive breeds of the original severum. Like all severums, a gold severum cichlid takes around one and a half to two years to grow into its adult size. The longest a gold severum can grow is 7.8 in (20 cm). They grow 1 inch (2.54 cm) per month.

Fish communicate by vision, scent, electrical impulse, and sound. Communication helps them to navigate within the water as well as during reproduction. Severum are semi-aggressive in nature and do not communicate well with other aggressive fish.
How big is a severum?
All species of severum are more or less similar. The length of red and gold severums is 7.8 in (20 cm) but a green severum measures around 8 in (20.3 cm) in length.
How fast can a severum swim?
The severum species is a big fan of free-swimming. They require large tanks that provide them with enough space for free swimming. However, their speed is not deduced.

Did you know...
Severum fish have a pharyngeal set of teeth present in their throat along with their normal set of teeth.
How many severum can live together?
A severum is a semi-aggressive fish, so larger tanks are required to hold them all together. In a 45 gal (205 l) tank, only a single cichlid can be present.
To add more fish, the tank size needs to be increased e.g. if you have three severums, you will need a 125 gal (568 l) tank. A breeding severum cichlid pair can be kept together in a tank size of 75 gal (341 l).
They are not really social fish, and therefore can survive alone. Since severums can sometimes be aggressive, it is best to keep them away from children.
How many species of severum are there?
There are currently five known species of the severum family. They are Heros severus, Heros efasciatus, Heros liberifer, Heros notatus, and Heros spurius.
The Heros severus is the most common severum. Some types of severum are also bred and produced in captivity. They are available in different color breeds and some of the most common severum species are the gold severum, the green severum, and the red severum.
