Nope, no anemone in there. Anemones require a lot of lighting and the tank needs to be well established before adding one. 1 pair of clowns will usually host the same anemone.
You don't really need an anemone to keep clowns. They may like it though. You don't need one unless you have a large tank and some aggressive tank mates possibly.
