Can a clownfish live in a 3 gallon tank?

A clownfish can technically survive in a 3-gallon tank, but it is not ideal for their long-term health. Clownfish require stable water conditions and enough space to swim and exhibit natural behaviors, which a small tank may not provide. Additionally, smaller tanks are more challenging to maintain in terms of water quality. A larger tank of at least 20 gallons is recommended for clownfish to thrive.
