I agree, some of the LPS seem to be pretty easy and quite forgiving, god knows I inadvertently abused my hammer, favia, and trumpets in their first year in my nano tank. They're now huge and I have to frag frequently to maintain their size. I started with 3 polyps of ultra green trumpets and now the colony is roughly 150 polyps, 1 polyp of Dragon Soul Favia has turned into roughly 50 polyps and my hammer was just one head and now it has to be at least 60 heads.
