So a question, I have something in my tank, I am not able to get a pic because it is at the back wall, about 8 inches in, so no way to get close enough. But it is very small, maybe between 1/4” and 3/8”. Definitely has tentacles. But the color is kind of burgundy. Is there a chance this is aptasia? Or something else? I think it is attached to a piece of macro algae, so I can get it out if need be. I just don’t want to remove something worth while.
