I think my anemone ate one of my Ocellaris clowns

I ordered this anemone from an online site and the guy told me that this anemone will host my clownfish. He called it a Haitian pink tip. Well both my clown fish were in the tank at 6 this morning but not at 4 when I got home. There is no way out for it to jump out.

Many things:
Condylactus anemones are caribbean and are not natural hosts for clowns. It may or may not be taken as a host by clowns.
It could eat a fish, but it is unlikely, IMO, unless the clown was not well.
How long have you had the clowns?
How old is your tank?
There are many places a dead clown could end up, especially if you have cleaners.
Your anemone will have specific lighting and water quality needs. They are definitely not easy to care for, so that may be an issue with the health of the anemone in time.
