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: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 8.5 - 9.0; dH range: 10 - 12; depth range 6 - 10 m (Ref. 49179). Tropical; 24°C - 26°C (Ref. 1672); 4°S - 8°S
Africa: endemic to Lake Tanganyika, occurs along the central east coast of the lake (Ref. 5713, 6770, 49179, 93901).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.5 cm TL male/unsexed; (Ref. 5713)
Occurs among rocks and stones in the littoral region of Lake Tanganyika; seldom strays more than 6 or 7 metres from a given area, even when pursued; found at depths between 6 and 10 metres (Ref. 49179). Feeds by grazing on rock biocover (Ref. 6770). Aquarium keeping: many females for one male; minimum aquarium size 150 cm (Ref. 51539).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00520 - 0.04832), b=2.99 (2.74 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (19 of 100) .
