Sorry, but no.
Tube anemonies are nonhosting anyhow.
Are the Tomatoes going to be the only inhabitants? They are some of the more territorial and aggresive. Certainly true when in a pair...IME anyway.
As Navarre has pointed out. Clowns will readily bed down in toadstools and various other easy to care for corals.
I fyou have your heart set on an anemonie however, I would go with a sebae. Mine has proven to be very hardy and seems to be one of the species more tolerant of varying conditions.
But as with all anemonies, lighting and good quality water conditions are very important. Not to mention, your tank must be matured, not just cycled to have succes with an anemonie.
