Diagnosis |
Andinoacara stalsbergi is a member of the Andinoacara rivulatus group. It closely resembles A. rivulatus with which it shares the comparatively large size (TL >200 mm in males), the color pattern of the cheeks and a light vertical stripe anterior and posterior to the rectangular midlateral spot. It can be easily diagnosed from this species by specific color characteristics, viz. having a conspicuous white margin in both the dorsal and caudal fin and on the body sides scales with light centers and contrasting dark marginal lines forming a fine reticulate pattern (Ref. 82770). |
