Do you expect your anemone to understand there is a device that is sucking in water?
Modify the filter (the penguin 330 is a HOB
filter...correct?) so that the bottom of the intake tube is a sponge instead of the strainer as mentioned above, that should help prevent it in the future.
The condy is evidently on the move again because it is not happy with its conditions. While being less demanding, do you still have some form of reef lighting? Do you have current possibly hitting it directly?
