Maksikirjon

Maksikirjon is a genus of small, colorful fish belonging to the family Cyprinidae. These fish are native to Southeast Asia, particularly found in the waters of Thailand, Laos, Cambodia, and Vietnam. They are commonly known as "harlequin rasboras" due to their distinctive coloration. The most well-known species, Triganalophus heteromorpha, is a popular aquarium fish.

Maksikirjons are characterized by their slender, torpedo-shaped bodies. Their most striking feature is the vibrant orange-red body color, which is marked by a prominent, triangular, iridescent blue-black or purple patch on their flank. This patch extends from behind the gill cover towards the tail. They also possess red fins, often with white or transparent tips. Males are generally smaller and more intensely colored than females.

These fish are schooling species and are best kept in groups of six or more individuals in their natural habitat, where they inhabit slow-moving streams, swamps, and flooded forest areas with abundant vegetation. In aquariums, they thrive in planted tanks with plenty of hiding places. They are omnivorous and their diet consists of small invertebrates, algae, and plant matter. Maksikirjons are peaceful and compatible with other small, similarly tempered fish. Their breeding behavior involves laying eggs on the underside of leaves, typically in the aquarium or in submerged vegetation in the wild.
