more than two clownfish?

I would say your tank is way to small for multiple clowns. What ponokareefer wrote is what I usually find to be true. The bigger the tank you have the better it will be for multiple clowns and the more peacefull clowns do better with one another then the more aggressive ones and it helps when you add them all at the same time.

I tried a black and white clown with my percs in my 230g tank and they never got along, the black and white always picked on the percs even though they hosted at opposite ends of the tank. However I have skunks and percs in there now and they all get along. But 230g is a lot bigger then 20g and I think if my tank was smaller they might not get along.
