Deposit eggs in caves at the ceiling, sometimes at the walls; female tends the clutch, male defends the territory; later both parents look after the free-swimming young. This corrects previous information from Ref. 13371.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00529 - 0.01890), b=3.16 (3.00 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
Daya lenting (Ref.
120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Fec=300-600).
Fishing Vulnerability (Ref.
