I am going to go with Sebae. Oral disk and column a uniform pale color. Stubby tentacles with purple or yellowish green tips. Also does not display, from your pic, any whiteish ring where the bubbles would be if it were bubbled.Cannot see the column but if you can look and it looks to be the same pale color as the oral disk is it is probably a good assumption that is a Sebae.
I am basing my guess on the above information which I got reading John Tullocks book Clownfish and Sea Anemones.
