The most common method for introducing new fish into an aquarium is to float the plastic bag for a while, then gradually mix the aquarium water with the fish store water in the bag. It works for many species, but there is a better way of introducing more sensitive fish into a new aquarium. The drip acclimation method sounds complicated; it’s really not. You can even buy a cheap drip acclimation kit from the on-line stores. Or you can make one.
Get about four feet of aquarium air hose, and put a regular air valve on one end. When you get the fish home, put them along with the aquarium store water into a clean plastic bucket that holds a couple gallons. Make sure to cover the bucket so the fish can’t jump out. Open the air valve all the way, and fill the air hose with water. Clip it to the inside of the aquarium that will hold the fish, and let the water syphon into the bucket. Adjust the output to a drip so the bucket takes about an hour to fill up most of the way. When the bucket is about full, remove the syphon and gently dump the fish into the aquarium.
If you buy one of the drip acclimation kits, they have a rigid, u-shaped tube on the intake end, so you you don’t have to bother with clipping the intake to the aquarium. They also have a plastic valve on the output end.
Drip acclimation will reduce much of the stress associated with moving fish from one environment to another. In my experience, it’s especially good for angelfish.

When done, do you move the fish with a net to the aquarium?
No. You just very gently pour the contents of the bucket, including fish, into the aquarium. Netting puts quite a bit of stress on a fish.
If you could find a way to get rid of the water from the store it would be extremely useful. I have a feeling that it would reduce the risk of the existing fish getting infected in diseases that the store has.
That’s why you should never buy a fish from an aquarium that has sick fish in it. If you just can’t resist, the fish should be isolated for a couple of weeks. Healthy fish can fight off many diseases and parasites, but a sudden change in their environment can compromise their immune system.
Wisely spoken :-)
So far, I have not lost a fish using the drip acclimation method. My latest test was on three fancy Guppies that were in transit for two days. Recently, one of the aquarium magazines mentioned that an aquarist took five hours to drip acclimate some very delicate fish. I believe the fish were captured from the wild.
i started using the drip method after hearing about it on this site some time ago and there is a notable difference in the fish when they are put into my aquariums, they seem far happier this way :)
hi all
i use a product called a fintro i find this much much easier then other methods if the link doesnt work let me know and i will find another way for you to find it

That looks interesting, and i suppose it would not be too difficult to make one. Of course, the bucket, air hose and a valve setup isn’t difficult either. They both accomplish the same thing. I don’t worry about using the water the fish came it, because the volume difference is so large (a cup or two versus a gallon or two).
