This species is rarely found in the aquarium trade. The species in the aquarium trade is rather the more common Heros efasciatus. Hybrids between the two are possible but unlikely because of different breeding behaviors, with Heros severus being a mouth brooding cichlid.
Common English names used of this species also include the convict fish, the deacon, the sedate cichlid, the severum and the striped cichlid.
The differences between the two Heros species are noticeable. H. efaciatus is a much larger fish at around 8-12" with a much larger girth and H. severus almost half that length and much more lightly built. H. efaciatus is available in a wide range of colours in the aquarium trade, but H. severus is usually a pale cream color with very small red spots, not too different from Heros notatus.
