I have zoas scattered all over my rocks, question is how do I frag them without moving the rock or taking out of the water....The rocks are big piece...Can i just cut the bottom of the zoas.? Thanks
I think there's good information in the Archives and FAQ section on this message board about fragging.
This website http://www.zoaid.com/articles003.php
has a pretty detailed article.
I've never done it, but I've been reading about it!
