Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Afterflossenstacheln: 0; Afterflossenweichstrahlen: 14. Diagnosis: scales distinctly larger above than below lateral-line; 8 teeth in outer tooth row of upper jaw; parietal fontanel absent (Ref. 2880, 81279).

Feeds on worms, insects and crustaceans. In aquaria, female lays up to 1000 eggs, after vigorous driving by the male, which hatch in 30 to 34 hours (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 100 cm (Ref. 51150).

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=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.32 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Fec=1000).

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

Preiskategorie (Ref. 80766): Unknown.
