Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.

Bayesian length-weight: a=0.01000 (0.00411 - 0.02433), b=3.06 (2.85 - 3.27), 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
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
