Direction

🐠 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! 😊

Really nice quality guppies. The colors became much stronger after a few days in my planted tank.

All my guppies arrived alive and healthy. Nice colors, active swimmers, and they started eating the same day.

Half Black Blue Guppy Fish

For close to two decades I've been getting "show quality Guppies" from three different IFGA breeders; truly the best of the best in the country. SO, what I'm about to say feels like blasphemy; but the Half Black Blue Delta Tail Guppies I just purchased are really nice. I'm curious to see what size they grow to, but otherwise I give these Guppies a 9 on a 10 scale.
