Male Crescent Bettas are more colorful than females, their brownish bodies displaying blue hues. There are distinct regional variations, with fish from Pinang Island being yellowish in color. Male Crescent Bettas are far from docile, especially when in breeding condition. If well fed, a pair of these bubble-nesting fish will spawn several times in quick succession, producing as many as 150 eggs per batch.
