I bought some time. I added some live rock/epoxy and glue a wall to separate them, for a little longer. The gig looked like a flame burned the tentacles it touched. It looks normal today.
The odd thing, I think I remember the mertensi touching my LTA/crispa/malu/misfit anemone, and they didn't mind touching. I think I remember this, they are getting close again, but that anemone is in a vinegar bottom, easy to move. I will get pic of those two touching before I move.
Those two may have built up tolerance to each other, been together a long time. Pete's blue gig is weak, it was weak when Pete had it too.
