Hi, I'm new to the forum but I've been reefing for about 6 years now. I have a 150 gallon tank that I bought and made everything else myself I have a 55 gallon sump that I sectioned off myself with a refugium. Which gets me to my question. I was doing my weekly cleaning yesterday and noticed something in my refugium and can't decide what it is? It is either an anenome of some sort? Or possibly a Duncan coral? I do have two Duncan corals in my display tank but I've never had any anenomes. So which also makes me question how did this get here. I haven't added anything into the tank in about year. So why is it just now appearing? I attached some photos any help would be appreciated. (don't mind it's a little dirty pics are before the cleaning haha)
Thanks in advance!
