I decided a while back that I had too many frag plugs with zoas on them so I separated the frags from the plugs then glued them to various spots on a flat piece of rock and a month or two later I noticed the polyps are all still colorful and almost double the size and twice as many. I bought a rasta polyp that has 8 polyps a month later and plan on doing the same thing they seem so tightly packed. .... Hopefully same results. ...
