About This Game

YOUR AQUARIUM IS A CARD COLLECTION

Every fish, shrimp, seahorse, plant and coral in ARC Aquarium is a collectible card. Open a pack, flip the cards, and watch them come alive in your tank. Fill four aquariums, merge duplicates up to ★10 and complete a collection book of 143 species and 120+ plants and corals.

EVERY CARD COMES ALIVE
