Description: A small and slender fish with large blue, iridescent eyes, giving them their common name. The body is whitish or green-yellow in color, while the fins have blue iridescence and spotted pattern with white edges. Several rows of body scales are edged in black. Three forms are known from northern Australia. These differ in the coloration of the upper pectoral fin rays, which can be yellow, orange or red. They have two dorsal fins, very close together, the first much smaller than the second.

Males are more colorful and have more elongated fins, have more spots on their fins, and are more brightly colored than females. Spotted Blue-eye should be spawned in groups, with a ratio of 2-3 males to 8-10 females. In this way we can get more eggs, and also it will help to give the females some rest, as males will chase the females quite relentlessly. Water should be around pH 7.5 and hard. Other breeders prefer acidic water (pH 5.5) to increase the chances of spawning. Use a small breeding tank with small clumps of fine-leaved plants, that can be used as a spawning medium such as densely grown java moss. The female Spotted Blue-eye will only release a small amount of eggs each day, usually 5-10 eggs every 24 hours. The eggs are adhesive and will stick to the fine leaves, and can be removed every 1-2 days. Place the spawning medium with the eggs in a separate container with water from the spawning tank. The eggs will hatch in 10-15 days, and the fry should be fed infusoria or liquifry until they are large enough to eat newly hatched brine shrimp.
