Breeding

This is an oviparous species. Breeding of these fish is very easy. You should breed these fish in a separate aquarium. Breeding tank should have soft water with slightly acidic pH,higher water temperature and low water level, dimmed light or no light at all, fine-leaved floating plants or fish hatchery, gentle but effective filtration system. You should separate males from females before the spawning and you should feed them with plenty of live food. You transfer selected pair of the fish (the thickest female and the most colourful male) in the breeding tank in the evening. The fish should spawn the next day in the morning, after intense courtships. You should immediately remove parents after spawning. The eggs hatch after 1 day. The fry starts to swim and feed 5-7 days later. The roe and fry are sensitive to light and water quality.
