yes this what i mean. i have never kept anthelia so i would not have thought of that but i would consider it a weed. quick proliferation doesnt mean invasive unless its a very aggressive coral around other corals like a galaxea. green star polyps are a weed and very aggressive. i mean for this to be a thread where people can come and look up their corals to see if they are particularly dangerous. xenia is invasive but not aggressive so you just need to trim but yellow polyps are aggressive.
