Hmmm...I’ve never “fragged” zoas before. My first zoas came to me as 4 polyps on a frag plug. Once they had multiplied and had started moving off the plug, I moved the plug to a new area, and the process began again. Maybe that could be considered a form of fragging. Here’s how my 4 little orange zoas ended up after 8 months through my 65 gal LPS tankThe tree gets its nutrients and water primarily from its roots and energy from leafs for photo synthesis.
Most corals get energy from polyps and flesh via light absorption.
if you cut the roots of a tree you don’t get faster growth. However if you micro frag and place the frags close to each other the fuse and grow faster. But only once the fuse do they accelerate growth. With zoas what doubles faster 1 polyp it 5. 5 or 20?
