🐟 Tetra Fish Care Guide
Tetras are small, colourful freshwater fish that are popular for community aquariums due to their peaceful nature and schooling behaviour.
📏 Tank Size
Minimum tank: 40–60 litres (10–15 gallons)
Larger tanks are recommended for bigger schools and stability
Long tanks are better than tall ones (they love horizontal swimming)
🌡 Water Parameters
Temperature: 22–26°C
pH: 6.0–7.5
Hardness: Soft to moderately hard
Ammonia/Nitrite: 0 ppm
Nitrate: < 20 ppm
⚠️ Stable water conditions are more important than “perfect” numbers.
🧑🤝🧑 Schooling Behaviour
Keep at least 6–10 tetras of the same species
Larger schools = better colour, less stress
Mixing different tetra species is fine in bigger tanks
🍽 Feeding
Omnivorous
Feed high-quality flakes or micro pellets
Supplement with:
Frozen or live foods (brine shrimp, daphnia, bloodworms)
Feed small amounts 1–2 times daily
💡 Uneaten food should be gone within 2 minutes.
🌿 Tank Setup
Use live plants or soft artificial plants
Dark substrate enhances colour
Provide open swimming space
Gentle filtration (strong flow stresses them)
🐠 Tank Mates
Good tank mates:
Other tetras
Rasboras
Corydoras
Small peaceful gouramis
Shrimp (with caution for very small shrimp)
Avoid:
Aggressive or fin-nipping fish
Large predatory species
