Teleostei (teleosts) > Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Pseudocrenilabrinae
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 Ecology

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

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 16.5 cm TL male/unsexed; (Ref. 5713)

Biology     Glossary (e.g. epibenthic)

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. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this 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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
