Yes, No, Maybe. For me BTA's have been easy. I have several. Of all the anemones I would have to say that E. Quads are the easiest to breed in captivity.
Many factors here, lighting, water quality, pH swings, and every tank is different.
I do not read alot of other posts where someones sebae or LTA or others have been bred in captivity. I have read where some carpet anemones have, and I have read of forced attempts at reproduction, by cutting or by use of rubberband.
