Was suprised to see a carpet anemone with two nemos, one about 5cm and the other about 2.5cm. Almost the entire lagoon at Big Sisters was filled with Sargassum seaweed. This anemone proved impossible to find after I moved away from it. The Sargassum cover was so thick that it covered huge portions of the area.
