Cucumbers and Anemones

[gberry]

I currently have a 9" LTA living in a 55 gal tank and have considered adding a sand sifting cucumber to the tank to help clean up the sand. What concerns me is that my LTA when fully expanded actually hits the front of the tank, making contact between the cucumber and the LTA inevitable. Does anyone have any experience with bottom dwelling anemones and sea cucumbers in the same tank they'd be willing to share? I'm kinda hesitant about adding the cucumber until I can figure out if the anemone will result in a dead or seriously mad cucumber and as a result, a dead tank. Thanks in advance!
