Morphology | Morphometrics
Can be separated from Rhynchocypris percnurus by having a long pointed conical projection on male genital papilla and body depth smaller than caudal peduncle length (Ref. 59043).
Occurs in swamps, backwaters (Ref. 59043) and rivers (Ref. 1441). A mature male measures 7.0 cm TL (Ref. 1441).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on size and trophs of closest relatives
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (35 of 100) .
