Etymology: Chromidotilapia: Greek, chromis = a fish, perhaps a perch + Bechuana, African native thiape = fish (Ref. 45335); melaniae: Named for Melanie Stiassny, curator of fishes at the American Museum of Natural History (Ref. 50577).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
; acqua dolce benthopelagico. Tropical
Africa: Ogooue, Ngounie and Nyanga Rivers, and coastal regions of central and southern Gabon (Ref. 81260).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 8.0 cm SL maschio/sesso non determinato; (Ref. 50577)
Spine dorsali (totale) : 13 - 15; Raggi dorsali molli (totale) : 9 - 12; Spine anali: 3; Raggi anali molli: 7 - 9; Vertebre: 25 - 27. Diagnosis: 14-18 gill rakers on first gill arch; no large spots on flanks (Ref. 81260). 4-6 bands or 2 rows of dark blotches and short horizontal lines usually visible when stressed (Ref. 50577, 81260). Relatively robust (body depth 26.7-38.2%, mean 34.4% SL); lachrymal depth less than 21% HL (Ref. 81260). No iridescence on cheek, operculum and flanks (Ref. 50577).
Prefers smaller rivers and creeks; normally found near the banks where plenty of hiding spots are available; diet consists primarily of small particles, preferably plant matter, although shrimp eggs and insect larvae are also taken (Ref. 52307). Monogamous (Ref. 52307), pair-bonding, ovophilic, biparental mouthbrooding species (Ref. 52307, 81260).
Life cycle and mating behavior
Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve
In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
