Having an aquarium is soothing and rewarding, but if you have limited space or money you may not be able to support a large tank of fish. Fortunately, there are many options available for nano salt water aquariums of 30 gallons or less. Many fish that are placed in nano aquariums will create their own territories within the small space, so make sure that, regardless of the size of your tank, you don’t overcrowd it. Check out this list of the 10 best fish to keep in smaller saltwater aquariums.
Clownfish: This is one of the most popular aquarium fish. While the orange and white variety is most recognizable, clownfish may also come in black and white, blue and other colors. Hearty eaters, clownfish require regular feedings in order to stay healthy.
Firefish: The firefish is a long specimen with a flowing tail and magnificent pointed fins. Its ethereal appearance makes it a great addition to your aquarium. The most common variety of firefish is white with a red tail, but they are also available in purple or blue.
Goby: The goby is a unique fish with an eel-like body and fins that are set close to its body. Its large eyes are its most defining feature. The goby comes in a variety of vibrant colors including electric blue and green with yellow stripes.
Clingfish: A long, narrow fish with a pointed snout and a striped body. Be aware that, unlike other aquarium fish, the clingfish is carnivorous and needs to be fed a diet of meat.
Cardinalfish: The red and orange cardinalfish is exceptionally docile. They can be kept in relatively large schools and make a peaceful addition to your aquarium.
Basslet: The basslet is a quick-moving striped fish. Always darting around, basslet can work up quite an appetite. They need to be fed at least twice a day if they are to thrive.

Blenny: The blenny is a striking fish decorated with white and black blocks of color. They are a little on the shy side and tend to do best in aquariums where they can carve out a space of their own as well as have places to hide.
Basslet: Vibrantly colored basslets are the rainbows of the aquarium. They come in varieties of bright purple, blue and indigo. Since they live in deep water, basslet tend to do best in aquariums where the lighting is slightly subdued and there are plenty of dark places to hide.
Tire Track Eel: The tire track eel is a long spiny eel with a mottled complexion and a pointed snout. Though still suitable for nano aquariums, tire track eels are on the large side and require a little extra room.
