The attraction allows people to walk inside a 2.2 million-litre tank, with the use of a special oxygen helmet.

The aquarium's press materials say that the 45-minute tour "doesn’t require any previous dive experience or training - only bathers [a swimming costume], a towel and a lot of courage".

Guests, who will be accompanied by a trainer, will be able to walk among sharks, giant stingrays and hundreds of fish.
