Saddle and Sharpnose Puffer

[Edmunds Reef]

I have a Saddle and Sharpnose Puffer. I have softies, and want to go the LPS's. Will they damage the corals?

I have a 100 Gal unit, that is about 2 years old.

New to me though.

Everything says they are "with caution" regarding reef tanks. I'd test it out, but go with a cheap frag of LPS.
