What anemone is this?

[balajeek15]

I have seen this in most of the clownfish hosting an anemone pictures/wallpapers with dark green tentacles, would like to know what anemone is this and would I be able to buy something like this or is this an photo effect?

Looks like a ritteri anemone.

Heteractis Magnifica (Ritteri is an old, now replaced identification name).

Yep ^ H. magnifica

Great, two questions:
1. My 90gal tank is year old and have few corals and fishes, should I wait for certain year level in order to have type of anemone?
2. If I can does this anemone come in varied color and I have to search for this specific color (looks dark or olive green) either in LFS or online.

Thanks.
