ive had my RBTA's under less wattage than that and they have survived... however my original RBTA that split into 2 was tank raised so it might have been under less wattage originally and thats why it was able to survive it....
now that i have upgraded to better lighting being originally PC to more PC now to a PC MH combo.... they are doing really good.... they have at least tripled in size .... like thomas says you are in the right ball park with lighting but its always iffy it depends on a lot of things to keep healthy anemones.... i have had 5 and 4 have survived and done very well... the one i lost was a sebae ..... the others RBTA and LTA's all have grown huge and look good.... you need a stable tank too so that they dont get stressed out....
with that wattage you should be able to keep most soft corals and LPS corals ...
ive kept bubble, frogspawn, hammer, toadstool, finger leather, xenia, zoo's, shrooms, colt, brain, flower pot (not recommended they dont survive long term) with that type of lighting ....
good luck!
