背面の脊椎 (合計) : 0; 背鰭 (合計) : 8; 肛門の骨: 0; 臀鰭: 10 - 11; 脊つい: 39 - 41. Diagnosis: Congoglanis sagitta differs from C. inga in having a shorter maxillary barbel, not reaching to vertical through anterior margin of orbit vs. extending well past anterior margin of orbit; a shallower caudal-peduncle depth, 6% of standard length vs. 7–8%; and more slender caudal peduncle, its depth 3.1–4.0 times in its length vs. 2.1–2.9; a shorter pelvic fin, 19–21% of standard length vs. 22–25%; a more anteriorly placed anal fin, its origin well in advance of tip of adpressed pelvic fin vs. origin approximately at tip of adpressed pelvic fin; shorter anal-fin rays, posterior rays of adpressed anal fin extend to, rarely slightly beyond, vertical through posterior limit of adipose fin vs. posterior rays extend well past vertical through posterior limit of adipose fin; and more vertebrae, 39–41 vs. 35–37 (Ref. 88958). It differs from C. alula in having a shorter pectoral fin, 23–27% of standard length vs. 28–29%; a shorter pelvic fin, 19–21% of standard length vs. 24–28%; a longer caudal peduncle, 21–24% of standard length vs. 18–22%; and more slender caudal peduncle, its depth 3.1–4.0 times in its length vs. 2.6–3.3 times; a relatively wide interorbital width, 2 times eye diameter vs. 1.5 times; a more anteriorly placed anal fin, its origin well in advance of tip of adpressed pelvic fin vs. origin approximately at tip of adpressed pelvic fin; and more vertebrae, 39–41 vs. 36–39 (Ref. 88958).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Congoglanis sagitta is typically found in the fastest flowing portions of rivers and are always associated with large rocks; they appear to congregate underneath rocks near where water breaks over the rocks during the day, and will move out onto the tops of rocks at night (Ref. 88958).
