🐟 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

🩺 Health & Care

Sensitive to sudden changes

Always acclimate slowly

Quarantine new fish when possible

Signs of stress:

Faded colour

Clamped fins

Hiding or erratic swimming

🧼 Maintenance

Weekly 20–30% water change

Clean filter media gently (tank water only)

Test water regularly

⏳ Lifespan

Average lifespan: 3–5 years

Good care = brighter colour + longer life
