Eggs are found attached to the substrate unguarded (Ref. 7043). From Ref. 7043, 'a ripe female is courted by males and when ready to spawn positions herself on vegetation, often vertically. A male mounts the female and clasps her back with his enlarged pelvic fins. The two fish vibrate and one to three eggs are deposited on living or dead vegetation.The pair moves to another spot and more eggs are laid.'
