Maturity: L_m ? range ? - ? cm
Max length : 10.0 cm TL hane/ej könsbestämd; (Ref. 86798)

Inhabits pools and backwaters of low-gradient creeks and small to large rivers (Ref. 86798). Oviparous, open substratum spawners (Ref. 205, 35784).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
