Assuming (always a bad thing) that the aquarium has (cycled) and ammonia and nitrites are zero each day all day,and you have Nitrates around 20 ppm up to 40 ppm Then I would acclimate the fish SLOWLY to your aquarium with one of two methods.
(1) Turn the lights off on the aquarium (less stress), and float the bag holding the fish for twenty minutes in your aquarium to allow them to adjust to the temperature. Then open the bag and either roll the top of the bag down three or four times like you might do with your socks ,and this should allow the bag to float upright in the water. or you may clip the bag to the side of the aquarium with some type of clip ,perhaps a large binder clip used to hold paper files,or maybe a clip such as those used to clip a bag of potato chips closed.
Next add approx 1/2 cup of water from your aquarium to the bag every four minutes.
Once the bag is near full,, carefully dump half the water from the bag taking care to do this over a bucket so as not to accidentally dump fish down the sink. Then ,,once again add about 1/2 cup of your aquarium water to the bag of fish every four minutes until once again, the bag is near full.
Then carefully net the fish from the bag of water and release them into your aquarium. Dump the water from the bag and or bucket down the sink .Do not add water from the bag or the bucket to your tank.
(2) This method requires that you gently empty the bag of fish into a CLEAN bucket that has not been used with chemicals (cleaning)or soap ,and tip the bucket so that the fishes are covered with water.A small block of wood placed under the bucket works well ,or a brick .
Then take a section of airline tubing approx three feet long, and tie a regular knot or perhaps two,, halfway down or near the middle of the tubing.
Then ,,stick one end of the tubing in your aquarium, and the other end should be in the bucket holding the fish. You then must suck on the end of the airline tubing from the bucket until water from your aquarium,begins to travel down the tube into the bucket holding fish.
You don't want a steady stream of water ,but a Dip,Drip,Drip, from your aquarium to the bucket holding the fish. If water is being drawn out too fast,,tighten the knot'(s) until you acheive the drip at approx three to four drips per second or two.
Once the water in the bucket is nearly as much as was in the bag of fish,,carefully dump about half of the water from the bucket,and once again allow the Drip,Drip,Drip.to again fill the bucket to where there is just as much water as was in the bag of fish originally.
Then carefully net the fish from the bucket and place them in your aquarium. Then dump the bucket of water down the sink.
This method can take anywhere from forty minutes, to a couple hours and I would recommend an hour minimum. Just keep allowing the water to drip,drip,drip,and when the bucket has more water than the bag of fish held,,dump half and repeat. Might also cover the bucket with a towel during the process to help keep stress to a minimum ,and to prevent fish from jumping out depending in large part on the depth of the bucket .
Would also recommend that lights in the aquarium be left off for the first 24 to 48 hours to allow the fish to adapt, and would not feed fish for the first 24 hours. New fish ,,trying to adapt to new surroundings,often refuse food and you don't need any excess waste laying about in the tank.
Perform weekly water changes of 25 to 50 percent,don't over feed the fish.don't overstock the tank. don't add too many fish at once,and Good Luck.8)
