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.

To ensure the health and longevity of aquarium fish, there are a number of factors that must be kept in a state of homeostasis. In some cases, including an algae eater can help protect against scum or buildup. Here’s how to know which aquariums need one.
What Is Aquarium Algae?
Algae are simple aquatic plants that thrive in water with higher levels of food or waste. Algae comes in a number of different varieties, with some forming a layer on the top of aquarium water and others building up on the sides of the tank. Although algae is natural and fish can coexist with it to some extent, large amounts of it can be problematic for fish, aquarium plants, and general aesthetic.
What Are Algae Eaters?
Although the term “algae eater” may summon to mind a small machine or cleaner, it actually refers to a specific type of fish. Some algae eaters such as plecos, otos, and the Siamese algae eater prefer to live off of algae, while others, such as molly, guppies, or rosy barbs, will only snack on it occasionally.
How to Determine If an Algae Eater Is Necessary
When considering adding an algae eater to a home aquarium, it’s important to remember that it involves adding an additional fish that requires its own care. Therefore, an algae eater should only be added if completely necessary. Before adding an algae eater, consider choosing other algae-busting tactics first. This includes ensuring the tank is properly maintained, switching to a higher quality filter, adding more live plants that will compete with algae growth, or scheduling fish feeding to minimize the amounts of uneaten food in the tank. If none of these methods work, an algae eater may be a necessary and helpful addition.
Choosing the Right Algae Eater
Before adding an algae eater, the first step is to consider the needs of the potential addition. For example, some algae eaters will only thrive if there is enough algae being produced regularly, as algae is their main source of nutrition. Additionally, the algae eater must be compatible with the other fish in the tank so that territoriality or aggression doesn’t become a problem. Finally, it’s important to ensure that the algae eater will survive in the temperature, pH, and water already in the tank. Because there is such a wide variety of algae eaters and algae, consult with an expert before purchasing an algae eater.
