I've had a lot of luck with non-grafted acros developing grafting in my systems. I attribute this to introducing grafted pieces into my systems and the grafting spreading "naturally". Today I discovered a colony of PC Rainbow developed a small amount of grafting near the base. I grabbed some quick unfiltered cell phone pics to share:
To develop this into a grafted acro I cut out the small bit that's developed grafting and mount it to a plug to let it grow out. In a year or two I'll be able to frag and propagate this coral. It should grow out with both the grafting and base colors, especially considering the grafting it significant.
