This little dude hitchhiked on my live rock.
He is moving around all over the place, what is he?..........

He is the pink little plant in the middle.

Haha, thanks, he isn't always puffed up like that though, when he does do that, he looks kind of scary. Aren't nennies hard to care for? My water parameters aren't right for the little guy either, will he survive until I can get them right for him tomorrow? Or should I take him out so he can grow somewhere else? Maybe at Idol, it's where he hitchhiked from. Hehe.

these little hitchhiker anemones do take care of themselves mostly.
