Pretty soon my xenia will be touching my yellow polyps, and my frogspawn is close to my button polyp colony. Are there any problems with any of these touching one another, if so I need to move them. Please advise, thanks.
One of two things will happen.
#1 The Xenia will grow over the Polyps.
Or
#2 The Polyps will grow over the Xenia.
If I was you, I would start cutting back both and keep a line between the two. I have the same problem with star polyps and Xenia. Every other week I cut both back and sell it to a LFS. Have not paid for anything recently... Hope this helps.
Watch out for that frogspawn, that will zap anything it touches!!!! Keep things out of its way!!
Xenia and polyps will grow over each other and smother one or the other from light and maybe current. But no immediate danger as far as touching.
Ok, one more, what about a finger leather? It may be in danger at some point too, and it's immovable, attached to 2 different rocks now. Thanks for the advice so far.
