The general purpose of acclimating your Tilapia fingerlings is to provide a gentle transition between two possibly different bodies of water.
Floating the bag.
1. (Do not open the shipping bag for this step) After you remove the sealed/inflated bag of Tilapia from the styrofoam box, place the bag into the (uncoordinated water) in your tank. Let the sealed bag float on top of the tank for fifteen minutes to allow the water in the shipping bag to adjust slowly to the temperature of the water in your tank.
2. Remove the band on the bag and roll the top edge of that bag down, to create an air pocket within the lip of the bag, allowing the bag to continue to float.
3. Add 1/2 cup of the tank water to the bag every five minutes, for fifteen minutes.
4. Net out the fingerlings, and add them to your tank. (Do not add the shipping water to your tank)
Be patient with the acclimating procedure and do not rush the process. The total time is about thirty minutes.
There is no need to add an air stone to the bag during the acclimation process.
Keep the tank lights off for a few hours after your fish are added to the tank.
The fish may go straight to the bottom for a few hours to adjust to their new environment. This is normal and does not mean anything is wrong with your fish.
