Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 7 - 10; Rückenflossenweichstrahlen (insgesamt) : 7; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 10 - 12.

Inhabits lowland swamps, drainage ditches and streams that have abundant vegetation (Ref. 2847). Occurs in slow-flowing streams, swampy ponds and billabongs with abundant aquatic vegetation. Temperature and pH ranges are 23°-28°C and 5.2-6.6, respectively (Ref. 44894). Most commonly found along the heavily vegetated margins of lily lagoons and small streams. Feeds mostly on diatoms and micro-crustaceans. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539). Well established in the aquarium hobby, but its longetivity is relatively brief, averaging only 2-3 years (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.34 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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

Preiskategorie (Ref. 80766): Unknown.
