This anemone was inside a coral tower, about 25 metres down. There was a kind of niche two thirds of the way up where the life was just incredible. There were anthias, glassfish in a corner and a lionfish as well as the anemone and the clown fish. I used the widest setting of my zoom to take the picture. Good buoyancy is also crucial to take pictures in a responsible way, without damaging the coral.
