Best Fish for a 10-Gallon Tank

Edited by Ivan F.

A 10-gallon is a popular first tank, and it fits more species than you might think, as long as you stock it lightly.

How we pick: Species whose minimum tank size is within 10% of 10 US gallons or smaller. Group size still counts: always check how many fish a species needs.

Fitting the same tank size does not mean these species can live together. Check each species' tank mates before you buy.
