    Wondering if anyone could help me ID this unknown white-clear "thing" on my LR I just noticed the other day. I'm not sure how long it's been there since it's toward the back of my tank where it's tough to see. I'm not sure if it's been growing at all either, but I'm going to keep an eye on it...

    Can anyone help me ID this thing? I think it has been in the tank for quite a while, but had not noticed it due to the way it blends it. It is not very large as you can tell from the button polyp in the backgroud and doesn't retract much if bothered. Thanks
