First foray into nems and corals. I got 2 Bubble tip nems a few days ago. They seem to have settled into their spot...both moved just a bit from where we placed them but not much and they haven't moved from "œtheir" chosen spot in 3 days now. Next week we (kids and I) want to add some corals. Daughter want some Zoas, Acans, and mushrooms, my son would like a torch and a hammer. How should we place them and what order should we add them or does it matter? Should we add the mushrooms on a rock by themselves? I've read they can tend to take over if not. What should not go next to each other?
