clownfish questions

[reefwars]

i have two clownfish in my 110g mixed reef ones a 1 1/2" skunk hosting a huge LTA and the other is a clarke the same size hes browsing a GBTA and wanders the tank.theyve never gotten along but since the skunk never leaves his anemone more than an inch or two theyve never had problems.a couple days ago i noticed they were coming out to meet each other at the nose then go away then yesterday i noticed the clarke shaking to the larger skunk. today when i got home from fragfest i noticed the two of them in the giant LTA only for a few seconds at a time but their rubbing against each other chasing and shaking . is it a possibility these two will mate or are they just curious??? ive had them both for several months
