There is a 1968 PhD dissertation (Stanford University) by Vicki Mabel Buchsbaum titled 'Behavioral and Physiological Responses to Light by the Sea Anemone Anthopleura elegantissima as Related to its Algal Symbionts'.  A significant portion of this thesis is addressed at the green fluorescence in this anemone, including experimental manipulations, and a brief discussion of fluorescence in other West Coast anemones.  Buchsbaum made the observation that the fluorescence only seemed to be associated with zooxanthellate specimens.

Some sea anemones in thePacific Northwest and British Columbia have
symbiotic algae, so perhaps those species might fluoresce.

The aggregating anemone Anthopleura elegantissima has zooxanthellae and
zoochlorellae and the giant green anemone, A. xanthogrammica, also has these
two symbionts according to Rita and Charles O'Clair in Southeast Alaska's
Rocy Shores - Animals.
