Tank has been up since November and is doing great. 38g three fish and just introduced some corals about a month and a half ago. My xenia and trumpet seem to be growing nicely. However, I have one zoa polyp that has not begun to spread at all. I still just have the one polyp. Should I expect more growth than this? Is it lighting? Admittedly I have only on sun Kronos 38watt led (mix white and blue 65/35) and one t8 blue actinic. I would like the zoa to spread a little quicker and grow? Is anything wrong or is this just the growth rate for Zoas? Not a single extra polyp in a month and a half.
