Choosing the best fish for your fish tank can be tricky for sure. But, if done right, you will have the right type of fish in your tank for the long haul. If you have no idea how to get started on this, then this guide is for you.

According to Live Aquaria, the first thing you need to do is to determine the category of fish that you would like to keep in your fish tank.

Determine the Category of Fish

To repeat what we mentioned earlier, there are over 3000 species of fish available. To help make your search for the right fish easier, we have divided the most commonly available tropical fish into 7 main categories. Each one of these categories contains fish that are similar in many of their traits. However, it should be emphasized that this listing is just an outline and there are often many unique differences between fish in the same family and individual research into each specific species should be done before making your final decision.
