> Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Pseudotropheus: Greek, pseudes = false + Greek, tropaion = defeat, a memorial of a fighting war, trophy; because of their specialized teeth were such an obvious feeding adaptation (Ref. 45335).

Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 17 - 19; Mjukstrålar i ryggfenan (totalt) : 8 - 9; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8 - 9. Diagnosis: This species is distinguished from all other members in Pseudotropheus, except P. williamsi, by a pale yellow to hyaline dorsal fin and by the absence of distinct vertical bars below the dorsal fin; most species of Pseudotropheus either have distinct bars below the dorsal fin or a dorsal fin with black pigment (Ref. 119458). It is distinguished from P. williamsi by the absence of two horizontal lines of black dots on the flank (Ref. 119458).

In some places, this species commonly inhabits open sandy areas which are usually below 10 m (Ref. 6256 mentions samples caught in trawls from 6-76 meters). It feeds by picking invertebrates from the silty layer that covers the sand in many places (Ref. 5595).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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).

Trofisk nivå (Ref. 69278): 4.0 ±0.0 se; based on diet studies.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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