Newbie question about clownfish behavior

[SaltHound]

Hello all. I am new to this and have a question about clownfish. I have a pair of young Common Clowns in my 32 gallon Biocube. They have been there for about a month now. Today I noticed the slightly larger clown swimming up to the slightly smaller clown and quivering its entire body for a second or two followed by chasing the smaller fish. At first I worried about parasites but this only happens when the larger Clown approaches the smaller Clown. Is this a mating behavior? Is it aggression? Both seem very healthy. Thank you in advance.

Perfectly normal behavior. Its them determining dominance between them :)
