Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7 - 11; Raggi dorsali molli (totale) : 8 - 13; Spine anali: 1; Raggi anali molli: 7 - 11.
Length in freshwater is recorded at 6.5 cm TL; in the sea, it is recorded at 8.5-9.0 cm TL (Ref. 2058). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00243 - 0.00942), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 se; based on size and trophs of closest relatives
Resilienza (Ref.
