Do you need to acclimate guppies?

Whether you are relocating your fish from another tank to a new one or just bought a new fish, Acclimatation is a must process for every fish to its new water.

How to Acclimate New Guppies?

You’ve returned from your local fish supply store with brand-new guppies. Now what?

While guppies are easy to care for, they require acclimation (like tropical fish) before placing in the new tank,

Don’t follow the store’s advice of floating the bag 15 minutes before releasing them into the tank water.

All this does is bring the water in the bag closer to the tank temperature,

but you need to worry about more than just water temperature to acclimate your fish.

How To Introduce Guppies To A New Tank?

Here’s the right way to acclimate new guppies.

When you bring your guppies home from the store in a bag, your guppies will be understandably stressed.

After all, the oxygen level in the water is dropping, the ammonia level is steadily rising, the pH is going down because of an increasing CO2 level,

and the water in the bag has a different salinity and temperature than the tank water.

Gradually acclimating your guppies is important because it gives them the best chance of staying healthy.

Option 1: Gradual Acclimation Method

This method will take a few hours. Start by floating the bag in your quarantine tank for about 30 minutes.

Now, slowly empty the bag into a five-gallon bucket, being sure there’s enough water for the fish to swim.

Cover the bucket to keep guppies from jumping out and then run airline tubing from bucket to quarantine tank.

Start a siphon and knot the tubing to ensure you get a flow of about 2-3 drops per second.

Let the water drip into the bucket until you have four times as much water as was in beginning.

Now net your guppy out and place it in your quarantine tank.

Option 2: Faster Acclimation Method

If you can’t wait, start by turning off aquarium lights then floating the bag for about 20 minutes.

Next, open the bag and allow it to float. Add about half a cup of tank water to the bag.

After 10 minutes, add another half cup of tank water to the bag. Repeat until the bag is nearly full.

Now, remove half of the water from the bag (and dispose of it without putting it back in the tank)

then repeat the process of adding tank water and waiting 10 minutes until the bag is nearly full again.

Net the fish out of the bag and add the guppy to your tank.

Keep your tank lights off for 12 hours or more to help your guppy adjust.

Note: If your guppy has been in the bag for more than 90 minutes,

Add a few drops of AmQuel Plus water conditioner to the bag before you start the process.

AmQuel Plus or a similar ammonia detoxifier protects your guppy by reducing ammonia, chlorine, nitrate, and nitrite from the water.
