Purchase surprise packs filled with delightful fish companions and nurture them through immersive, relaxing mini-games. Feed your fish with care, maintain the perfect water temperature, clean the air filters to ensure healthy conditions, and gently scrub aquarium walls to keep your aquatic heaven crystal clear.
