I thought ball anemones were okay. I've got a bunch in my tank. And by bunch I mean like six. That I can see.

some ball anemones on the underside of a rock ended up being the reason that my tank buddy couldnt put any livestock on top of it... after they realized it was there and killed it, the problem was gone.

They are okay... I've never killed the ones in my tank. I like them. :)

I never had any problems with them either, in fact I grew quite fond of them.
