Rayons mous dorsaux (Total) : 5 - 6; Rayons mous anaux: 13 - 16; Vertèbres: 27 - 29. Upper and lower edge of caudal fin with bright orange margins (Ref. 43281).

Inhabits shallow permanent standing water of ditches, canals and ponds. Most commonly found in water that has dense growth of submerged aquatic macrophytes with finely divided leaves. Feeds on plankton. Caught only with fine-meshed nets or when larger nets pull out large amounts of plants, trapping the fishes in them. Not seen in the markets (Ref. 12693). Non-annual breeder. Is very difficult to maintain in aquarium (Ref. 27139).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00190 - 0.01207), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.45 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fec < 100).

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

Catégorie de prix (Ref. 80766): Unknown.
