संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 8 - 9; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 12; गुदा कांटा: 3; ऐनल सौफट रेज़: 8. This large-sized species of Geophagus (largest type 19.8 cm SL), differs from its congeners in having the following characters: a well developed and complete infraorbital stripe; rectangular midlateral spot; entire caudal fin with large irregularly arranged light roundish spots; a comparatively high number of dorsal fin spines (XVIII or XIX ); 34 -36 scales in E1 row (Ref. 78437).
Body shape (shape guide): elongated.
This species apparently prefers bare sandy bottoms among rocky areas in the black water tributaries of the upper Orinoco, and which may have a remarkably strong current. Water data collected in January at a collecting site: pH 4.5; electrical conductivity 10 μS/cm;
temperature 28°C. The type locality at río Sipapo has brownish water, moderately
clear with pH 5.15 and a temperature of 29.5 °C. Reported associated fish fauna includes Aequidens sp. 'Atabapo', Biotodoma wavrini, Crenicichla sp. 'Atabapo', Laetacara sp. 'Orangefl ossen', Heros severus, Mesonauta insignis, and several characid and siluroid species (Ref. 78437).
