Fish generally thrive when given a lot of space, but some fish are better suited to smaller tanks, or “nano aquariums.” For those who want to enjoy aquariums on a smaller scale, these fish are great for a nano aquarium.
The Scarlet Badis, also known as the Dario Dario, is a nano aquarium fish that resembles the dwarf cichlid. The peaceful but timid nature of the Scarlet Badis can make it tricky to feed, as it often hides from the aquarist. But these fish will happily coexist with other nano fish and feed off of live brine shrimp, daphnia, and banana worms.
Betta fish are commonly sold in small containers, and while it’s true they can live in small spaces for a short period of time, they generally want at least five gallons of water to feel happiest. Although Bettas are easy to care for, they don’t play nice with other fish as the Scarlet Badis does, so it’s best to keep them alone.
Apart from their unique bumblebee-like coloring, Gobies are also an attractive pick for nano tanks because they can exist in both freshwater and brackish tanks. Because they only grow to about 1.5 inches in size, they may seem innocuous, but these Gobies can be somewhat aggressive and should only be paired with more peaceful fish.
The smallest member of the Gourami family, the Sparkling, or “Pygmy” Gourami thrive best in tanks with a lot of foliage. These fish are peaceful, and when fed a mixture of plant- and meat-based flakes, will develop beautiful “sparkling” colors. Sparkling Gourami are social fish, so it’s best to purchase three or more for a nano tank.
Pros and Cons of Nano Tanks
Because nano tanks are smaller in size, they can be easier for new fish owners to manage and maintain. However, because of their size, they may also require more frequent maintenance, such as water changes, balancing pH, and cleaning. Additionally, owners should regularly test their water for toxins, as problems can become quickly fatal due to the relatively condensed nature of the environment. Nano tanks are a great introduction to aquarium ownership, and there are numerous beautiful fish that do well in small spaces.
