> 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).
Eponymy: Jean Dubois was a limnologist and a colleague of the author, Georges Marlier. [...] (Ref. 128868), visit book page.

Maturity: L_m ? range ? - ? cm
Max length : 12.0 cm TL mâle / non sexé; (Ref. 5713)

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 based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
