I have a larger snowflake clownfish around two inches long, and a smaller 1 1/4 inch long orange storm. When first introduced they were fine but the smaller clown gets bullied for food, and gets his fins nipped or latched onto by the larger clownfish, and they will lock jaws somethimes. When the larger clown comes up to the smaller one, the small one turns sideways but does not wiggle, and that will often result in a fin nip or being chased. Not sure if it is just you clowns figuring things out or if it is something else. I figured it was possible i bought a female (the small one) and the larger clownfish turned into a female. However they get along 1 in three or four days. My tank is about a year old thanks for any help!
