Actinopteri (ray-finned fishes) > 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
Freshwater; demersal; pH range: 7.0 - 9.0; dH range: 10 - 15; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 24°C - 26°C (Ref. 2060); 4°S - 10°S
Africa: Endemic to Lake Tanganyika but does not occur in both ends of the lake.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 5713)
Do not form schools. Occurs over solid rock, either anchored and part of the hard core of the coast, interlocking rubble, or even sandstone slabs lining a beach but not loose pebbles rolling about in the surf or silted habitats (Ref. 6770).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±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 (12 of 100) .
