Inhabits near-shore surface waters. Firm flesh is highly valued (Ref. 4967). Largest African cichlid (Ref. 4537).
Deposits eggs in abandoned nests of other cichlids, in between stones, or in the sand, if no nests are available (Ref. 7343).

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Nível Trófico (Ref.
69278): 4.5 ±0.80 se; based on food items.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliência (Ref.
