Etymology: Tropheus: Greek, tropaion = defeat, a memorial of a fighting war, trophy; because of their specialized teeth were such an obvious feeding adaptation (Ref. 45335).
Environment / Climate / Range
Freshwater; demersal; pH range: 8.5 - 9.0; dH range: 10 - 12. Tropical; 24°C - 26°C (Ref. 1672); 3°S - 6°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 5713)
Africa: endemic to Lake Tanganyika, patchy distribution in the northern part of the lake (Ref. 6770, 46829, 97323).
Prefers the upper rocky habitat where it feeds on the algae attached to the rocks (Ref. 7343, 46829). Occurs to a depth of 30 m; maternal mouthbrooder; females guard their offspring for a few days after releasing them for first time (Ref. 46829). Aquarium keeping: many females for one male; minimum aquarium size 150 cm (Ref. 51539).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00508 - 0.03119), b=3.03 (2.81 - 3.25), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
