[Ebook] 500 freshwater aquarium fish – Cichlids – Severum Cichlid (Heros severus)

The Severum is an old favorite (first imported in 1909) that has held its own against strong competition from other species. The species occurs in three color forms: green, gold, and blue-green. The wild form is usually a brownish green color. About eight or nine vertical bands appear on the body. They are more pronounced in juveniles, but the band nearest the caudal fin retains its dark coloration.
