they have a lot of information about anemones and also problems people have encountered with owning ones.
We own a Sebae and it has lived quite a few months, but I really wish I had read the above board before I did, my clown doesn't host the anemone, it hosts a leather toadstool you can check it out in my gallery, it used to host an giant cup mushroom which it decided to lure our other clown into and was eaten one night.
We don't have the Giant cup anymore

The anemone we have sits at the back of our tank where it not only gets the light from our
PC lights but also the
PC light that we have on our hang on refugium. When people write that an anemone is "hardy or better for a beginner, do the research on other people's experiences first.
JMO good luck in your decision
