The main attraction here is a 45-minute 'Behind the Tanks' tour that visits the aquarium's kitchen, laboratory and tanks. Offered daily, it is unexpectedly fascinating (who knew that a turtle eats kilos of salad every day?). Front of house, the stars of the show are reef sharks, seahorses and huge green sea turtles Ari and Cuba. The Napoleon fish with their prominent and familiar profiles provide a laugh. Upstairs there's a reptile area featuring a chameleon and gloriously green iguana.
