We visited a free aquarium/hatchery. It was nothing fancy, mostly big concrete holding tanks full of salt water fish but the fish themselves were fascinating. There was a boardwalk which went out over a pond full of fish the length of my niece plus an extra hundred pounds! We heard a large smack in the water and turned to see a large sea turtle surfacing! There was an eel and starfish with patterns we had never seen before.The fish swam beneath back and forth beneath our feet.
