funny story. i bought an established reef from a friend locally and he had crazy loads of large vermetids that i spent hours gluing over to get ready for sps and then i go to another local reefer that was giving out some frags and he gave me this acro that had three vermetids and a barnacle all encrusted over. i wouldve left it just to enjoy the cohabiting diversity if the coral were to continue its growth rate from the other reefer but since i knew it would significantly slow i glued over immediately.
