Adding a Yellow Tang -- always last??

[geno]

I want to add a yellow tang and a sailfin tang to my reef tank. So, naturally, I have a question for the experienced ones

1. Can I put both tangs in at the same time without much concern (125g)?

2. Is either likely to harm my LPS coral (frogspawn, anchor, and daisy)

3. Is either likely to harm my clam (crocea)?

I've read that a yellow tank should be added last since they are so territorial. I do have plans for a few other fish -- so, if that's a factor, I'll hold off on the yellow tang.

What other fish you adding? If no more tangs, go ahead and put both in at the same time. Sailfins can be equally aggressive so those dont matter. And for what its worth, my TY doesn't really like my sailfin. He'll chase him around the tank for no reason what so ever. And no they wont bother any corals or clams.
