Краткое описание
определительные ключи | морфология | морфометрия
Body robust and of moderate depth. Males with long gonopodium, but not reaching base of tail. Each side with 4 (rarely 3 or 5) round or oval black blotches the size of the pupil (Ref. 36880).
Collected from two creeks with slow current and from a small stagnant puddle at 40 m elevation; at temperatures between 26-34°C. Swims in small aggregations among vegetation or in shallow waters. Feeds on diatoms, desmids and detritus (Ref. 36880). Observed to occur in 10 to 50 cm deep (Ref. 26130).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
