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).
Eponymy: John Johns was a collector of Lake Malawi fishes for the aquarium trade. ‘Johann’ is a German variant of John. Unfortunately, we have no further information about him. (Ref. 128868), visit book page.

ライフサイクルと交尾行動 成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Maternal mouthbrooders; males establish territories and maintain a harem of females; female deposits eggs and picks them up in the mouth for incubation; male spreads out his anal fin showing the "eggs pots"; the females mistake these spots for her eggs and try to also take them inside her mouth; the male then releases his milt and the female takes them in, thus fertilizing the eggs inside her mouth (Ref. 44091).
