One guppy seemed weak at first, so I kept it in quarantine overnight. It recovered well and now the whole group is healthy.

🐠 How to Acclimate New Guppy Fish
🔹 📦 Unpack Carefully – Gently remove the bag containing your guppies from the shipping box.
🔹 🌡️ Float to Match Temperature – Place the sealed bag in your tank for 15-20 minutes to equalize water temperature.
🔹 💧 Drip Acclimate – Slowly add small amounts of tank water to the bag every 5 minutes for about 30-45 minutes.
🔹 🏠 Release Gently – Use a net to transfer the guppies into the tank, avoiding adding bag water.
🔹 💡 Dim the Lights – Reduce lighting for a few hours to minimize stress.
🔹 🌊 Monitor Behavior – Guppies may be shy at first; allow them time to explore.
🔹 🛡️ Check Water Parameters – Ensure pH, temperature, and ammonia levels match their needs.
🔹 🍽️ Wait Before Feeding – Feed after 4-6 hours once they’ve adjusted.
With proper acclimation, your guppies will settle in quickly and thrive in their new home! 😊
