it's a Ritteri also known commonly as a magnificent. They will get HUGE if they are given proper nutrients. The tentacles get a nice emerald green with purple tips (most common morph) and the base gets a very deep purple (more purple than it already is). Nice anemone good luck with it.
Was sold has a long tentacule anemone, but now the guy of the shop who has some knowledge think the young kid made a mistake and sold me a magnifica.(my tomato and two percula love it)
I got two anemone this week end and I am not sure of their kind on both of them, I would appreciate if the sellers could put the write name in their shop, so I could stop guessing and trying to find my answer on the net and with your help guys.
