What's happening to my birdsnest frag?

[04scoobysti]

i have a birdsnest that is in contact with some gsp and no ill affects. They both seem to be keeping their eachother at bay, if anything the gsp has recided a bit where they contact. But ive definitly had sps stung by ricordia, and in my experience the bleaching has been localized to the contact area.
