Gold severum
A variant of Severum (Heros efasciatus)

A xanthic golden-yellow line, often with red speckling on the face of males. One of the oldest and most widely available aquarium-bred severum forms.
Keeper tips for this variant
The gold body shows nitrate-driven 'pepper' spotting easily — keep water pristine, as the pale base makes any stress blotching or HITH (hole-in-the-head) pitting far more visible than on green fish.
