簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 9 - 10; 脊椎骨: 40 - 41. Can be diagnosed in having the following characters: lateral line scales 39-42 (vs. 43-54; except 34-35 in Hemibrycon orcesi); scales between lateral line and anal-fin origin 6-7 (vs. 4-5; except 7-9 in Hemibrycon colombianus); and scales between lateral line and dorsal-fin origin 6-7 (vs. 8; except 7-10 in Hemibrycon colombianus). Most specimens of Hemibrycon paez differ from those of Hemibrycon boquiae, Hemibrycon yacopiae and Hemibrycon raqueliae by the possession of 19-23 anal-fin rays (vs. 23-29); readily distinguished from its congeners by having the mesopterygoid barely touching the metapterygoid (vs. overlapping the metapterygoid, except in Hemibrycon jabonero, Hemibrycon rafaelense and Hemibrycon guppyi) (Ref. 83529).
Inhabits creeks with surface temperature 19.2-20.5°C, air temperature 18.8-22.8°C, dissolved oxygen 7.6-8.0mg/l, saturation 98-100%, clear water, width 5-6m, and substrate composed of stone, sand and decaying organic material (Ref. 83529).
