Just like Swordtails, I believe Bosemani Rainbowfish need hard alakline water.
Has a very limited natural range, being known only from an area of three lakes known as Ajamaru, in the remote Vogelkop Peninsula of Irian Jaya, and from nearby Lakes Hain and Aitinjo. The rainbows tend to congregate in the clear shallows of the lakes, where aquatic vegetation grows very densely. The lakes are characterised by hard, alkaline water (pH 8.0-9.0), although the fish are also found in some surrounding tributaries with wildly different water chemistry (pH 6.0-6.5).
