So 260 watts of PC lighting, I really can't talk about PC as I've never had them. My BTA's do well in 380 watts of VHO, they live and reproduce, sometimes all to often. I estimate that you are still a little on the low side of lighting for anemones and I would rather you don't try any.
However if you must then look into researching the BTA, RBTA, E-Quadricolors or Haitian anemones.
