I have no idea never bough it, was just floating through the tank one day though it was a bright green paly.
Put it in its current spot and now after months it is about size of nickle? but no new heads have formed?
Kind of thinking is not a Paly.... Bright green with yelllow green center.
Couple pic - one open and one of it eating - loves to grab food when feeding the fish...
I agree looks like a strain of a majono anenome. Get rid of it while you can. I made the mistake in thinking it was alright to have a couple here and there when i bought 150lbs of rock. They are little, but pack a huge punch on sps. Worst thing next to hair algae in my opinion. They will detach and find a nice crevasse to settle in or find a nice home on your prized sps and sting the heck out of it. Pretty hard to get rid of once they start multiplying.
OK I found this so assuming that what it is doing and its a majono anemone - as its growing buds
Aiptasia reproduce asexually by pedal laceration. Small masses of cells are pinched or torn off the margins of the pedal disk forming small buds. These grow slowly into buds and within a week or two after completely separating from the foot the bud develops a mouth and small tentacles and begins to feed on its own. Some of these clones will release and be distributed in the water column to colonize other locations. Additionally, Aiptasia demonstrates a preferential tolerance to its own clones and will not sting them. This allows large groupings of Aiptasia clones to form as a result of asexual reproduction.
Actually I just saw a pic ( in the selling forum) of another paly/zoa that looks just like this except it's red. It was called a tiger tail. You may want to look it up, you may have a new morph. Just curious is it located in an area of really high flow, if so, thats why the skirt is so long and flowing.
