Pink tip condy anemones are one of the most hardy and easiest to care for, but they aren't natural hosts to clowns. If you want an anemone to host your clowns you could try a BTA.
What other corals/inverts/fish do you have?
How long has your tank been setup? I would recommend the tank to be at least 6 months old before attempting an anemone.
What are your water parameters?
