Essential care information for new and existing owners.
Life expectancy for betta fish is typically 2-4 years with proper care.
Habitat
Betta fish require a properly sized, filtered tank. Small bowls are not suitable for long-term care.
Minimum tank size:
- At least 20 litres (5 gallons)
A proper setup should include:
- Gentle filter (bettas prefer low flow)
- Heater for stable temperature
- Plants and hiding spots
Bettas breathe air using a labyrinth organ, so always ensure access to the surface.
Diet
Bettas are carnivorous and need a high-protein diet.
Main diet:
- High-quality betta pellets
- Feed 1–2 times daily
Treats:
- Bloodworms, brine shrimp, daphnia
- Feed 1–2 times per week
Avoid overfeeding — their stomach is about the size of their eye.
Temperature & Water
- Ideal temperature: 24–28°C
- Use a heater to keep water stable
- Perform 25–50% water changes weekly
- Always use dechlorinated water
Sudden temperature changes can cause stress and illness.
Behaviour & Compatibility
Bettas are known for their strong personalities and territorial nature.
- Males should be kept alone
- May attack other fish with long fins
- Can recognise their owners
Provide enrichment like plants and decor to reduce boredom and stress.
Care & Maintenance
- Check water parameters regularly
- Remove uneaten food
- Clean tank gently (don’t over-clean)
Bettas are hardy but still require consistent care and a clean environment.
