This is a comprehensive tier list of some common and uncommon nano fish. The rankings will be placed on how well they do with other fish, personalities, care requirements, and how well they can do within tank sizes between 5-30 gallons (since this is a nano fish list). So, fish that do well in tanks between 5-30 gallons will do better than fish that can only be in 20-30 gallons. Rankings furthermore that are closer to the right side are ranked lower than fish towards the left.
