Dropped down on west wall and stayed along side of vertical wall for ~30 mins, then across top of reef at 20-30 feet rest of dive. Near end saw a green sea turtle! Huge coral formations, fans, chimneys, etc. Beautiful water, so clear we could see it dim as the sky clouded up above. Started getting chilly around 30 mins. So many fish! Parrotfish, surgeonfish, angelfish, bannerfish- a surgeon fish all black with a white stripe at the base of dorsal and ventral fins. Also an angel fish with a big false eye on the body. School of barracudas came by. We got to watch the turtle for a long time as it swam back and forth. Dive felt great buoyancy & easy. Drifted and swam parts of it as current picked up toward end of dive.
