Rookie coral person here. I just bought some Zoa frag plugs for my aquarium (and one Duncan). I just wedged the frags into gaps in the rock for now and didn't glue them or anything. They're stable in place and I don't think they're going to get knocked over. My question is, how do you get them on the rocks? I'm afraid of doing anything like scraping them off and sticking them to the rock because my frags don't have enough polyps for many do-overs. What am I supposed to do? Should I just leave them to grow over the frag and eventually onto the rock (and maybe move the frag somewhere else after to grow more in a different spot), or is there some other way to get the zoas on the rocks?
