Feed small amounts 2–3 times daily, ensuring all food is consumed within 2–3 minutes. Include sinking pellets, leafy greens, occasional frozen/live foods. Avoid overfeeding to prevent swim bladder and digestive issues.
Egg scatterers; spawn in spring or early summer, no parental care, eggs may be eaten if not separated
Breeding is triggered by temperature and seasonal changes. Males develop small white tubercles on gill covers and fins. Females become rounder when carrying eggs. Spawning occurs in shallow areas or among plants, eggs hatch in 2–7 days depending on water temperature.
Requires strong filtration and regular water changes (30–50% weekly). Maintain ammonia and nitrites at 0 ppm; nitrates under 40 ppm. Good aeration and oxygenation are crucial due to their high activity levels.
Prone to swim bladder problems (especially from overfeeding or dry pellets), ich (white spot disease), fin rot, and bacterial infections. Poor water quality increases risk of illness.
