🐟 Why Are My Fish Gasping at the Surface?

When fish rush to the surface for air, it signals something is wrong. Here’s what could be happening:

---

🌬️ Oxygen Problems

• 🐠 Overstocking → Too many fish = low O₂
• 🌡️ High Temps → Warm water holds less oxygen
• 🌊 Poor Surface Movement → Little gas exchange
• 🌱 Plants at Night → They use oxygen in the dark

✅ Fix: Add an air stone 💨, ripple surface 🌊, reduce stocking 🐟, keep temps stable 🌡️

---

💧 Water Quality Issues

• ☠️ Ammonia (NH₃) → Burns gills, even at 0.25 ppm
• 🧪 Nitrite (NO₂⁻) → Causes “brown blood disease”
• 🚫 High Nitrate (NO₃⁻) → Weakens fish long-term

✅ Fix: Test water 🧪, do weekly changes 🪣, boost filtration 🌀

---

🦠 Gill Diseases & Parasites

• 🐛 Gill Flukes → Tiny worms on gills
• 🧫 Bacterial Gill Disease → Slimy coating
• 🍄 Fungal Infections → White growths
• 🔥 Chemical Burns → From untreated tap water

✅ Fix: Inspect gills 👀, quarantine sick fish 🏥, treat with meds 💊

---

⚗️ Chemical Contamination

• 🧴 Chlorine/Chloramine → Deadly if untreated
• 🏭 Heavy Metals → Copper, lead, zinc from pipes
• 🏠 Household Sprays → Cleaners, perfumes, smoke

✅ Fix: Always dechlorinate 💧, use Prime/conditioner, cover tank during cleaning 🚫🧴

📝 Pro Tips

• 🪣 Change 20–30% water weekly
• 🌊 Keep surface moving for oxygen exchange
• 🧪 Test ammonia, nitrite, nitrate often
• 🚫 Don’t overfeed (rotting food = bad water)
• 📄 Ask your water supplier for a full water report and confirm if they use chlorine only or chloramine

⚠️ Bottom Line:
If your fish are gasping, act fast → check oxygen 🌬️, test water 🧪, and confirm tap water safety 💧.
