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).

Maturity: Lm ?  range ? - ? cm
Max length : 9.4 cm SL male/unsexed; (Ref. 5684)
Occurs in all kinds of habitats but if most frequently found in large caves or near large boulders. Feeds on anything that is available but is specialized in cleaning parasites from the catfish Bagrus meridionalis (Ref. 5595).
