As of today, peak season now, through ~December 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.
The Lake Kutubu rainbowfish (Melanotaenia lacustris) is endemic to Lake Kutubu and its outlet the Soro River, Papua New Guinea.
Adults deposit adhesive eggs on submerged vegetation and in Characeae/algal beds.
In this tropical, highland lake the species breeds continuously rather than in a single short seasonal pulse, with daily peaks often around first light.
