My Chromis are kissing!? They in love?

[reefmaster]

Hey, one day, i looked into my tank and 2 of my chromis were kissing eachother with thier lips. They did it 2 or 3 times, and then stopped. Ive always noticed that they seem to follow around together always. Do you think they might mate?

That's not kissing...at least not to fish. Generally, lip locking is a dominance type behavior to see who's stronger.
