0 nitrites or ammonia, nitrates 0-5, ph 8.2, calcium 400, lighting is 150w metal halide which is about 16 cm above the anemone, temp. is a tad low at 24 C. It had been attached to a rock that I had placed on the top of the branch coral. Maybe it did not like the surface of the rock as it was rough with some crevases. It is sure suctioned on hard to the glass. I don't mind the that it is on the back glass, actually looks cool, just a bit unnatural.
