That's not what I wanted to hear...lol o well guess time to kill it. It's been a while I forgot can I kill it with lemon juice??????? It is bright green in the center just hard to get a good picture. Also it pulls back all the way in when I poke it.
not sure baout lemon juice. if you can frag off that section and even lose some of the zoas around it, thats what i would do. those zoas grow fast generally
