Clowns probably will not host in the Condylactis Anemone. It happens on rare occasions but for the most part it wont. This is not a good choice for anemone as you are learning they tend to walk about the tank constantly. Keep an eye on things as you may find the anemone stuck in a power head or the intake to a HOB
filter (if you have one) watch out for it getting near you overflows as well.
As ezy33 said, anemones should be added to mature tanks (8+ months old) with strong lighting.
