It'll host clowns, but it's not as likely to happen than with other anemones. Condy anemones are not natural hosts to any clownfish since they come from different oceans.
For a tank that size you might as well just go with T-5 or MH lights. 4 or 6x54 watt T-5HO lights or 2x150 watt DE halides would be great.
