Red rainbowfish breeding sparring behavior
Description
The males are bright red and with age grow a high back. The females are olive brown in colour. Their colours change depending on their mood, but subordinate males do not display bright colours. They grow up to 15 cm (5.9 in) in size, but typically attain a smaller size of around 12 cm (4.7 in).
Breeding

They are an egg scattering species and they scatter their eggs among clumps of vegetation. The eggs take about 7 days to hatch.
Nutrition

Glossolepis incisus is an omnivore and in captivity it will eat most common commercial aquarium foods readily. It may be slightly more carnivorous than most of the Australian rainbowfish.
Conservation status

The IUCN Red List classifies Glossolepis incisus as vulnerable. This is because of the rapidly increasing human population around this fish's only natural habitat and introduced species such as tilapia.
Distribution

This species is endemic to Lake Sentani and its tributaries near Jayapura in Papua, Indonesia (a range it shares with the related Chilatherina sentaniensis).
