The beautiful Green terror cichlid sold in the aquarium hobby under the names Silver Saum, Silbersaum and White Saum has finally been described by scientists.
Previously believed a colour variant of the Green terror, Andinoacara (formerly Aequidens) rivulatus , the new species has been named Andinoacara stalsbergi by Zuzana Musilova, Ingo Schindler and Wolfgang Staeck.
A. stalsbergi, which is named after Alf Stalsberg, can be found in trans-Andean rivers and lakes along the Peruvian Pacific coastline of South America between the Rio Chira in the north and Rio Pisco in the south.
As fishkeepers have known for the past 40 years, it differs from the Green terror, Andinoacara rivulatus, in having a silvery white rather than an orange edge to the fins.
The scales of stalsbergi also have pale centres and dark margins that form a reticulate pattern on the flanks.
