Remarks: Blue Hole Rainbowfish (Melanotaenia sp.) were originally considered to be a variant of Melaenotaenia affinis, however recent genetic studies have shown them to be separate species. They are extremely rare in the hobby. This line was collected by Gary Lange and bred in the US. The photos are credited to Jimmy Walker.
Blue Hole Rainbows, sometimes called Bongo Rainbowfish after the village near their collection point, are small, steel-blue fish with a navy horizontal stripe from their snout to the caudal fin. Below the stripe is a white stripe running parallel, followed by a dark blue patch that fills out the rest of the abdomen. Their unpaired fins are light blue and finish in a purple-red.
The fish are omnivorous and should be fed a quality flake food with supplemental proteins such as baby brine shrimp. They require clean water but tolerate a wide variety of water parameters. By providing frequent water changes, you will be rewarded with nearly continuous spawning attempts. Melanotaenia species deposit eggs in weedy areas (often mimicked by a yarn mop) and the eggs hatch 7-10 days later. Eggs can be harvested for hatching in separate tanks to avoid predation. Most Rainbows show their best colors at sunrise, when the males display their bright fins for potential mates. Having more females than males will allow for proper color displays and avoid any unwanted aggression towards lone females.
