The first, and probably most important, decision you will make is if the fish will be freshwater fish or saltwater fish. Both freshwater and saltwater fish have coldwater and tropical fish. When choosing fish to raise, the freshwater fish tend to be easier. An example of freshwater, coldwater fish is the goldfish. This is one of the easiest fish to raise and a really good choice for a first time fish owner. If you choose to go with tropical freshwater fish the colors are more vibrant and you can put more of these fish into a tank. If this does not sound like it is for you then you should look into saltwater fish. Choosing fish that are saltwater means that you will need to add "sea mix" into the water. Also, you can not put aquarium plants into a saltwater fish ank.
Next, when choosing fish you need to make sure that the fish that you are buying are healthy. Many times fish can die from disease or stress. You should not purchase a fish that is brand new to the store. Give it about two weeks to settle in to make sure that it is healthy. There are a few things to look for in a healthy fish. Choosing fish that have dense colors and that colors do not buffer on fish with paterns. The fish should also be able to swim with fins erect, stay still, and have a well fixed body contour. A few ways to keep from choosing unhealthy fish is by looking for a colorless trail of excreta, bumps on the fish, or protruding scales. Also the fish should not sink or bob while swimming, swim with fins against body, or stay in the corner alone. Looking for these things will help you to in choosing fish that are healthy.
Last, you must remember the size of the fish when choosing fish. It is important to make sure that your fish is not to big for the tank. When you purchase the fish remember that it will double in size. A rule of thumb is that if a fish has big eyes and big scales it will be a big fish.
Keeping these things in mind will get you on your way to a beautiful fish tank. Remember the things that matter are freshwater, saltwater, health and size when deciding what fish is right for you. Now that you know all you need to know in choosing fish you are ready to enjoy the experience of your new swimming friends.
