Upcoming are some growth progressions of each SPS coral since starting back up with sticks. You'll notice the diminished polyp extension from May/June to October. This is from my Genicanthus lamarck angelfish which while I was told that genicanthus angels are not polyp nippers, mine certainly is. The nipping hasn't significantly affected the growth rate of my acropora but the growth form has become more compact and the corallites are more distinct, I believe in an attempt to shield the polyps. When I check the tank when all the lights are out, polyp extension is the same as it always has been over the nighttime.
And before someone thinks it has to do with feeding, she gets fed 6-7 times a day and forages constantly for other food including SPS polyps.
