Glossolepis incisa

Glossolepis incisa is a species of rainbowfish from the Lake Sentani region of Papua, Indonesia, and is widely known in the aquarium hobby as the red rainbowfish or combscale rainbowfish. Glossolepis incisa is especially admired for the intense red coloration developed by mature males, along with a deep body shape and reflective scales that make groups of this species highly attractive in spacious freshwater aquariums. Understanding Glossolepis incisa is important because juveniles and females are usually more subdued in color, while the full beauty of the species appears gradually through maturity, social display, and stable care. In aquarium keeping, this active schooling fish benefits from clean, well-oxygenated water, open swimming space, a balanced diet, and peaceful tankmates of similar size, while its restricted natural range also makes habitat awareness and responsible captive maintenance important parts of appreciating the species.
