Mumbai's aquarium is worth a visit as much for the striking building – a fabulous Art Deco mansion covered in motifs of fish and waves – as for the fishtanks inside. The detailing even extends to the wrought iron sharks on the gates. The collection features plenty of reef fish, plus turtles and other exotic species, along with oddities like the 'Quran fish' whose scales have a remarkable resemblance to an Arabic inscription.
