Nudibranch mating pair

Hello everyone and thanks for taking the time to check out my photo. I went out this past weekend and shot these nubranchs mating. Unfortunately the background here is pretty Dull. I live in Maui and with nothing but hard corals it's tough to get alot of color in one photo. But here we go.

They're not mating, they're trailing (a characteristic of Risbecia species):

Nice shot by the way.

Thanks for the link and the info. I found a couple diffrent pairs and thoughts since theye had been slightly overlapping I automatically figured it was a form of mating or courtship. Thanks
