; 新鮮な水 底生の漂泳性; 深さの範囲 6 - ? m (Ref. 35835). Tropical; 13°N - 11°N
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 63.5 cm FL オス/雌雄の選別がない; (Ref. 35835)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 11 - 13; 肛門の骨: 0; 臀鰭: 8. Body depth 1 to 1.1 times in head length; ventral fin length less than 1.7 times in head length; nuchal hump starts gradually at occiput; silvery white.
Occurs especially over muddy and sandy substrates all over the lake, preferably in water deeper than 6 m. A benthivore that at a larger size turns into a piscivore. Specimens smaller than 15 cm FL mainly eat insect larvae. Mollusks and plant material become more important with increased size. When fish reach sizes of 25 cm FL or more, fish are their main food.

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 3.4 ±0.50 se; based on food items.
回復力 (Ref.
