Irian Red Rainbowfish (Glossolepis incisus)

Glossolepis incisus is known as the Irian Red Rainbow or the Salmon Red Rainbow. Females are a gold-bronze color, while males are mostly red with the occasional bronze sheen over scales. They are often collected near the shoreline in Lake Sentani, the only lake they are known to inhabit. They appreciate plenty of submerged vegetation.

The fish are omnivorous and should be fed 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. Glossolepis 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 toward lone females.
