Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335).
Eponymy: Hans-Joachim Mayland (1928–2004) was a German ichthyologist, aquarist, photographer and writer. [...] John Lombardo of ‘African Fish Imports’ first brought this species to Burgess’ attention and provided the holotype. He also coined the name ‘Peacocks’ for the Aulonocara genus.

Maturity: Lm ? range ? - ? cm
Max length : 8.7 cm SL 雄魚/尚未辨別雌雄; (Ref. 5684)
Inhabits the sediment-rich regions and is often found over sandy and muddy patches between rocks. Abundant in waters > 10 m (Ref. 6256). Feeds by brushing the loose algae from the rocks and also on plankton in open water (Ref. 5595). Aggressive males exhibit territoriality over sand-dug nests. Females, juveniles and non-territorial adult males occur singly or in small groups (Ref. 6256). All males have only one eggspot on the anal fin (Ref. 47814).
棲息於沉澱物-豐饒的區域而且時常發現在在岩石之間的沙泥區塊上面了。 豐富的在水域 >10 公尺中.(參考文獻 6256) 吃藉由疏刷鬆散的藻類從岩石以及在浮游生物上在開放的水域中.(參考文獻 5595) 在沙子上的侵略性雄性展現領域性-挖了巢。 雌性, 稚魚與非具有領域性雄性成魚各別地或形成小群魚群出現。 (參考文獻 6256)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Females are mouthbrooders (Ref. 2060). Males adorn one eggspot on the anal fin which mimics eggs and apparently functions to lure females to pick up this egg enabling fertilization of the rest of the eggs being brooded in the females's mouth (Ref. 47814). In one experimental study, females are attracted to males with one large eggspot more than to those with numerous tiny eggs covering the same area (Ref. 47814).非洲: Mbenji 島，馬拉威湖的特有種。 引進了 Namalenje 島。
