The current was very strong - great if you know where you are going and want to get there fast. Bad if you're a new-again diver and have never seen the route before. I just kept a close eye on the dive master.
In my three dives I saw wiggling fish [more than just a general observation - it was two particular fish and it was probably a communication behavior], zig-zag gaping clams [a personal favorite of mine], spiraling yellow 'Christmas tree' coral filtering mouths pull in quickly to their rock like base when I passed over, a large polka dot fish that had small polka dots in the large polka dots, zig-zag topped fish, one highly venomous [making rattle snakes seem like wimps] sea snake, shrimp smaller than a pea. Some fish were super bright; others were highly camouflaged. All were very interesting.
