Im wondering if the aquarium is running and what procedures are required during covid

They are open, just the usual; wear your mask, social distance and protocols for going up the stairs.

Nothing prebook your tickets and visit on time

Buy a timed ticket online however if you arrive outside the time they have been honoring them still. Restrictions you must wear masks and you are supposed to social distance but be weary most of the other guests are not.

They are only allowing so many people in at a time and they encourage people to purchase their tickets online if possible. Some exhibits are not running but otherwise everything else is the same.
