Oktedi rainbowfish (Melanotaenia oktediensis)
The rainbowfishes are a family of small, colourful, freshwater fish that are found in northern and eastern Australia and New Guinea and some other nearby islands.
In Oktedi rainbowfish , body colouration is coppery brown above a prominent mid-lateral line and pale mauve to white below. Body slender and laterally compressed but depth increasing with age. Two dorsal fins, very close together, the first much smaller than the second. May reach a maximum size of 12 cm, but usually less than 10 cm.
Spawning occurs from October to December, with females producing between 100 and 200 eggs. Eggs adhere to water plants and hatching occurs around 9 to 12 days at temperatures between 24 to 28° Celsius. Essentially a carnivore, their natural diet consists of terrestrial insects, small aquatic crustaceans, and insect larvae. Aquatic algae, plant pollens, and small pulpy seeds are also ingested.
