axelrodi

The 10 gallon aquarium is one of the most common aquarium sizes. Its also usually what the beginner aquarist starts with. The 10 gallon poses its own set of challenges because it is such a small volume of water, but that does not mean it is not a viable tank to create a beautiful aquatic ecosystem.  This is a list of fairly hardy species that could live in a 10 gallon aquarium.  This list also includes some that you can make your own decisions as well about adding to your new aquarium. There are also some “biotope” ideas at the end of this guide to give some ideas.

Cardinal Tetra (Paracheirodon axelrodi)

Cardinal tetras, and their relatives the neon tetra, are a species of freshwater schooling fish native to South America. Their iridescent blue stripe is thought to work as a defense mechanism to avoid being eaten. The reflective stripe may disorientate predators, especially when many fish are swimming together, making it harder to pick out a single fish.
