Collections/Nano Tank

Best Nano Tank Fish

Nano reef keeping proves that great things come in small packages. These species thrive in tanks of 30 gallons or less, making them ideal for desktop aquariums, office setups, and hobbyists with limited space.

304 species suitable for nano tanks (30 gallons or under).

Nano Tank Tips

  • Smaller water volumes are less stable -- stay on top of water changes and parameter testing.
  • Stock conservatively. Even if a fish fits in a nano tank, fewer fish means more stable water quality.
  • Choose species with peaceful temperaments to reduce territorial stress in tight quarters.
