Can anyone tell me what this is? Just appeared in my tank about 10-15 minutes ago. I added some corals about week ago but I do not have anything that looks like this.
Does not look like the images I have seen for aiptasia.
I do Not believe it’s Aptasia or majanos. I do t recognize it as any common pests- maybe some coral was on the rock? Do you have any large polyp zenia? Kind of looks like one head of large zenia.
