Spend quiet days with your fish in a little aquarium. Pasterium C is a 3D aquarium set in a softly muted pastel room, where you enjoy everyday life with your fish. You start with three little fish in a fishbowl. Give them names, feed them, and watch them slowly grow and bond with you. - Every fish has its own personality and looks Even fish of the same kind each have something special. Keep an eye on growth, bond, and health on each fish’s card. Fish that feel weak can get care, or rest at boarding. - A life that grows a little every day New friends and ornaments arrive, and sometimes eggs are laid. On day 7 the living room tank opens, and on day 14 you get an auto feeder you can use in any tank. - Make the tank your own Choose plants, ornaments, sand colors, and lighting to decorate. Save up to 5 favorite layouts for each tank. - Learn about creatures and ornaments in your journal Look back on each day in the diary, and read about each one in the creature and ornament guides. - Shifting light and gentle sounds The light in the room changes from morning to night and with the seasons. Watch your fish from underwater, and keep photos or short videos. Choose between the original music and lofi, with different tracks for morning, day, and night. You can choose your tap sounds too. - Start for free, then visit the study or the round tank The fishbowl and the living room are free. “Study with a Bookshelf” and “Sunset City & Round Tank” are each a one-time in-app purchase. The study adds a big tank about 120 cm wide, along with Discus, Arowana, River Stingray, and Axolotl. The round tank adds a glass tank about 130 cm across by a window over a sunset city, a lighthouse harbor, and 4 new kinds: Penguin Tetra, White Cloud Minnow, Glass Catfish, and White Medaka. Available in Japanese, English, Korean, Arabic, Simplified and Traditional Chinese, Spanish, French, German, and Portuguese. No ads and no account sign-up. Everyday play works offline.
