This aquarium has a series of themed areas showcasing Filipino marine life, including a clear 25m tunnel that puts visitors right in the thick of things. Children will enjoy the chance to touch starfish and take a ride in a glass-bottomed boat (PHP150). One of the quirkier attractions is the opportunity to have the dead skin from your toes nibbled by little "doctor fish" for PHP120. Avoid weekends and public holidays, when the place is packed to capacity.
