Every clownfish is going to need at least ten gallons of space. If you’re going to buy one clownfish, then a 10-gallon fish tank would be just big enough for that fish. Most choose to keep clownfish in pairs. You’ll want a 20-gallon tank or a tank that is somewhat larger to keep the fish happy and healthy.
