I bought Clowns initially because I wanted a tough enough dither / target school to go with rambunctious Central American cichlids. Lots of guys keep them with their tough cichlids, so I thought I'd try them out. The result? I like them as much or more than the centrals which were my passion in the hobby. The are constantly out and "playing" during the day, very active, colorful and cool looking, social with each other, they get pretty big, and they live a long time and are resilient. Just very cool fish, and they still do great with bigger mean central americans. They are also more tame than my centrals (they hand feed). A school / shoal of clowns in a large tank (they need it) is as good as it gets for color, personality, and activity level. Nothing not to love unless you have a small tank.
