Nano tanks are popular in the aquarium industry because they are convenient while still allowing hobbyists to obtain beautiful and graceful pets. Ranging from 5 gallons to 30 gallons, nano fish tanks can be placed on desks, in offices, in bedrooms, and on small stands.
If you are considering starting a nano reef tank, you may wish to know what types of saltwater fish and freshwater fish live well in these smaller environments.
Fortunately, you have many options, and they’re all good ones.

Not as Simple as It Looks
If you have never owned a fish tank, it may be tempting to try to start with a nano tank.
Keep in mind that a smaller tank will likely get dirty faster, as there is not as much water to help maintain a proper pH level. For that reason, regular water changes are crucial to the health of your fish and to maintain the beauty of your aquarium design.
Because it’s a small living space, it’s also important to choose fish that are likely to be compatible and to include components such as gravel and plants.
