Hi twistedpro,
Yes, the anemone is a malu.
I'll keep an eye on the clowns sizewise, thanks for the tip. Although I think they're Percula Clowns rather than Clark's.
Regarding the Sclerospongiae coral, which one do you mean? Unfortunately I'm not always the best in the LFS for getting the name, I usually say "can I have that one please?" and point

Regarding food, I feed Cyclop-eeze and live food, alternating daily, along with live marine phytoplankton about twice a week. I've also just got some frozen snails and a turkey baster for a more direct way of feeding the anemone, suggested by my LFS. I will check out the other stuff you mentioned though.
Cheers!
Thanks, David.
