Etymology: Trematochromis: Greek, trematos = hole + Greek, chromis, = a fish, perhaps a perch (Ref. 45335).
Issue
The correct allocation to Haplochromis or Ctenochromis is pending further taxonomic studies (Ref. 57075).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
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.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.45 se; based on food items.
回复力 (Ref.
