Life cycle and mating behavior

Prior to spawning a pair selects and cleans a nest site, usually in a rocky crevice. Female deposits about 30 eggs. Male guards and fans the eggs. Eggs hatch in about 6 days.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00391 - 0.02676), b=3.02 (2.79 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
