Predominantly found in open offshore waters, sometimes found close to the shore in sandy areas (Ref. 4983). As suggested by its long and coiled intestines, H. nigripinnis is a vegetarian. It feeds mainly on suspended phytoplankton. Like most Haplochromis species, it is an opportunistic feeder (Ref. 558).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00693 - 0.03016), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
