Where did you come from?!?!

[CheckSix187]

Hey guys, haven't been on here in a while. So i just got a chance to come home from my college house and I notice these green polyp looking things in one area of the tank, i haven't added anything to my tank since last winters frag swap, so i have no clue why these guys are suddenly popping up.

I just want to know if they're gonna cause my any trouble and if anyones seen them before.

Thanks guys!

Possible Mojano Anemone.

Looks like Majano. They are bad.

You will definitely want to get rid of them. Worse than Aptasia IMO. Search for Majano Wand. That is a tool to rid your tank of them.
