Diagnosis: 3 rows of scales between anterior parts of upper and lower lateral line; lips fleshy; upper edge of lower jaw horizontal when mouth is closed (Ref. 7378, 52307, 52346, 53405). Lower jaw teeth on a distinctly shelf-like elevated processus on dentary in juveniles and mature females (Ref. 7378).
Prefers brackish water but is also found further upstream in rivers (Ref. 3032). Opportunistic benthic macrophage (Ref. 52346). Prefers insects and their larvae; maternal mouthbrooder that does not pair-bond (Ref. 52307).

Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00868 - 0.03645), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 2.7 ±0.33 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=0.7).
Kwetsbaarheid (Ref.
59153): Low vulnerability (22 of 100) .
