🐟 Betta Fish (Betta splendens) Care Guide
Difficulty: Beginner → IntermediateSize: 2.5–3 inchesTemperament: Semi-aggressive (especially males)Lifespan: 3–5 years
💧 Tank Setup
  • Tank Size: 5 gallons minimum — more space = less stress.
  • Water Range: 78–82 °F, pH 6.5–7.5.
  • Filtration: Gentle flow — strong current tires them out.
  • Decor: Plants, caves, and leaf hammocks near the surface for resting.
  • Lighting: Moderate; they prefer consistent light cycles over intensity.
💡 Lesser-Known Tip: Bettas breathe air from the surface with their labyrinth organ — keep a small pocket of warm air above the water (a lid helps maintain humidity and health).
🍽️ Diet
  • Staple: High-protein betta pellets.
  • Treats: Frozen or live bloodworms, daphnia, and brine shrimp.
  • Feeding Rule: 2–3 pellets twice daily — fast them one day a week to prevent bloating.
💡 Fact: Bettas can recognize their owners’ faces and even learn feeding routines — consistent hand placement builds trust!
🧬 Breeding Behavior
  • Type: Bubble-nest builder.
  • Pairing: Introduce female in a transparent container inside male’s tank for 1–2 days first.
  • Trigger: Add floating plants + drop temperature slightly before release.
  • Parental Care: Male guards the nest and returns fallen eggs — remove female after spawning.
💡 Breeder Insight: Use Indian almond leaves — they release tannins that strengthen eggs, reduce bacteria, and naturally tint the water.
🤝 Tank Mates
Peaceful options include kuhli loaches, small rasboras, ember tetras, and snails.Avoid fin-nippers or other male bettas (never keep two males together).
