Can you put cold water fish straight into a new tank?

The short answer is no, you should not put cold water fish straight into a new tank.

The long answer is that fish have a natural fear of water that is cold or unfamiliar. This fear can cause them to struggle and even die in a new tank.

It’s best to introduce them gradually over a period of several days or weeks, by slowly introducing them to the tank one or two at a time. If you must put them all in at once, make sure the tank is large enough for them to move around in and that the water is at room temperature.


It depends on a number of factors, including the type of fish you are adding and the size of the tank. A good rule of thumb, however, is to allow the water to sit for at least 24 hours before adding any fish.

This will give the water time to adjust to the new environment and ensure that your fish are as healthy as possible.
