Tatarstan's first oceanarium is populated by rays, a seal, some iguanas, penguins, sharks, crocodiles, swans, and a 130-year old tortoise, to name only a few of its 3,000 plus species of animals, birds and fishes. For the young visitors, they offer contests and educational games here from time to time. Free tickets for the aquarium can be won in an online lottery. To play, subscribe to aquarium news or follow the aquarium on VKontakte social network.
