Heinz, Wayne and I ventured out of Botany Bay to Bypass reef.  Water looked good and it did not disappoint.  At the bottom we were anchored 10m north of the cave. Viz was a good 15m and the water nice and warm at 19 degrees.  Lots of mowong hanging around the cave.  Wayne found the sea horses on the rock adjacent to the cave and to our surprise there was a third one.  This one was swimming under a ledge which was great to watch.  We rarely see sea horses swimming, mostly they are just sitting hanging on to a sea tulip.  It's good to see more sea horses around the area.
