Blessings Aquarium Guide
Betta fish (also called Siamese Fighting Fish) are one of the most popular aquarium pets in India. They’re colorful, easy to keep, and perfect for small spaces — but they still need proper care. This guide explains everything a beginner needs to know to keep their Betta healthy and happy.

1. Minimum Tank Size
Most people think Bettas can live in tiny bowls — this is false.
✔ Recommended Size: 10–15 liters (minimum)
✔ Better: 20 liters with a filter
Why? Bettas produce ammonia. In a small bowl, ammonia builds up fast and makes them sick.
2. Do Bettas Need a Filter?
YES.A filter keeps the water clean and builds beneficial bacteria.
Best filter types for Bettas:
Sponge Filter (gentle flow)
Internal Filter with flow control
Hang-on-Back (HOB) Filter with low flow
Avoid strong currents — Bettas have long fins and get tired easily.
3. Water Temperature
Bettas are tropical fish.
✔ Temperature: 26–28°C✔ Use a small aquarium heater
❌ Don’t keep Bettas in cold weather (especially Pune winters)
Cold water → fin clamping, color loss, no eating.
4. What to Feed Your Betta
Feed a protein-rich diet.
Best foods:
Betta pellets (high protein)
Freeze-dried bloodworms
Frozen daphnia
Brine shrimp
Feeding rule:✔ 2 times a day✔ 2–3 pellets per meal✔ 1 “fasting day” per week (prevents bloating)
Avoid:
❌ Bread
❌ Human food
❌ Overfeeding
5. Tank Setup for Betta
Plants (recommended)
Live plants reduce stress:
Anubias
Amazon sword
Vallisneria
Java fern
Floating plants (Salvinia, Amazon forbit)
Decoration
Use smooth, rounded decor. Sharp edges tear fins.
Lighting
Normal aquarium LED is enough. Keep lights on for 8 hours/day.
6. Water Changes
For a 10–20 liter tank:
✔ 30–40% water change weekly
✔ Use dechlorinate always
✔ Siphon waste from bottom
Do NOT change all water at once — it removes good bacteria.
7. Betta Temperament: Tank Mates or Not?
Bettas can be aggressive. Safe tank mates (if tank is 30L+):
Shrimp (sometimes safe)
Small snails
Peaceful small fish (neon tetras, glow light tetras — but depends on personality)
Avoid:
❌ Guppies (color triggers attacks)
❌ Other male Bettas
❌ Long-fin fish
For beginners → Keep Betta alone = safest.
8. Signs Your Betta Is Stressed or Sick

⚠ Fin clamping
