About
Endemic to the Ajamaru Lakes of West Papua, Melanotaenia boesemani inhabits clear, hard, alkaline water and thrives in well-maintained community aquariums. Males develop their full bicolour splendour over 12–18 months, making them a rewarding long-term project. Keep in groups of six or more to encourage natural display behaviour and reduce individual stress.
