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: John Edmund Sharrock Moore (1870–1947) was a British biologist, zoologist and cytologist who studied at the Royal College of Science, South Kensington (now part of Imperial College, London). [...] (Ref. 128868), visit book page.

Adults are solitary (Ref. 86760). Feed on worms, crustaceans, insects and plant matter (Ref. 7020). Females brood their young in the mouth (Ref. 86760). Aquarium keeping: feed on epiphyton; many females for one male; minimum aquarium size 150 cm (Ref. 51539).

Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Female lays only a few eggs. Female collects eggs up into her mouth before they sink to the bottom and then moves to the genital area of the male. There the sperm are shed and taken into the mouth of the female where fertilization takes place. Eggs hatch after about 4 weeks of incubation (Ref. 7020). Produces 5-17 eggs (Ref. 1672). In one study, eggs from the cleavage phase and larvae of up to 1.45 cm TL are mouthbrooded by female parents ranging from 6.2 to 7.9 cm SL long (Ref. 86760).
