Before adding a fish to a new aquarium, it would be wise to create an appropriate environment first. For instance, you can choose the rocks you want to have at the bottom, any decorations and plants as places to hide for the fish, and the right chemicals and foods that you are going to need.

Another thing to do, in order for the fish tank to work well and support life, there has to be a balance of bacteria in the water that agrees with life. If your tank does not have this good bacteria, your fish are not going to last long.

Many experts recommend that you set up your tank, start the filter and air, and let it run for four to six weeks before you consider adding fish. This makes the water ideal for them when they do arrive, and they are more likely to survive.

Once this time has passed and the water is indeed as it should be (look for help and kits to let you know that this is the case), you can then add your fish. If you follow all of these instructions, your aquarium fresh water fish have a much better chance of surviving.

Of course, you may get lucky and put your aquarium fresh water fish right into a new tank and they will do well. However, for the most part, this is not going to happen.
