Three Nano- Sized Tetras for Small Aquariums

by Cass Fan


Tetra fish are a stellar choice for small aquariums, including nano tanks.
They are small, peaceful fish that come in a wide range of colors and patterns, and they can add beauty and activity to the tank.

Some of the more popular Tetra species for nano tanks include Green Neon Tetras, Fire Ember Tetras, and Long Fin White Skirt Tetras.

Here are some quick profiles:

  • Green Neon Tetras:

    Green Neon Tetras are related to the perrenially popular Neon Tetra, but are somewhat less common. They are known for their vibrant colors and peaceful nature. Green Neons are small, reaching a maximum size of about one and a half inches, and they are well-suited to life in a small tank.

 



  • Fire Ember Tetras:

    Fire ember tetras are tiny fish that are native to South America. They are only about half an inch in length, and they have a bright red body with faint black markings. They are peaceful and easy to care for, and they can add a pop of color to a nano tank. 
    These guys are quite timid, and need the company of their own kind to school with and feel safe. Plus.. they look absolutely glorious en masse! Plan on getting at least a dozen.



  • Long Fin White Skirt Tetras:

    These Long-finned variants of the popular White Skirt Tetras are a calm, schooling nano fish originating in South American rivers. This species (Gymnocorymbus ternetzi) is a dreamy nano alternative to aggressive Angelfish, and they display strong schooling behaviors. You'll love watching a group hover and dart as one!


These three tiny Tetras are great choices for a nano aquarium. They are small, peaceful, and colorful, and they can add beauty and activity to the tank.

There are a ton of different tetra species out there to choose from, so you can pick the one that best suits your tank and your personal preferences.

Be sure to do your research!

  • Um… I’m not sure I’m comfortable with white skirt and black skirt tetras being called “nano” fish, especially when compared to the likes of green neon and ember tetras.

    Contrary to popular belief, these guys can get up to 3 inches long and need a 30 gallon tank as the bare minimum.
