Flyspecked Hardyhead are found in a variety of tropical rivers, creeks, lakes, ponds and impoundments including fast-flowing water. Generally prefers shallow water over a sand, gravel or muddy substrate with aquatic vegetation. Shaols of the species may be found in still or slow moving sections of streams.
Spawning is believed to be stimulated by increased water temperature and photo-period, with a peak in spawning has been observed in spring and early summere. The eggs are adhesive and are laid amongst aquatic vegetation or amongst emergent vegetation near the water's edge. No parental care has been observed.
