Morphology | Morphometrics
In subfamily Acheilognathinae (Genera Acheilognathus and Rhodeus ), female possesses an ovipositor which is used for depositing eggs inside the bivalves. Juveniles hatch and stay in the bivalve until they can swim (Ref. 43281).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00452 - 0.02213), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.2 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
