Read full descriptionHide full description
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 The fishbowl and the living room are free. “Study with a Bookshelf” is a one-time in-app purchase. It adds a big tank about 120 cm wide, along with Discus, Arowana, River Stingray, and Axolotl. 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. Buying and restoring the in-app purchase needs a connection. Your fish, diary, and other records are saved in the app. Deleting the app also deletes these records, but photos and videos you saved to the Photos app remain.

Verdict
The clearest difference is in-app purchases: GEMPIXEL | Pixel Art Puzzle at none against Pasterium C's 1. Pasterium C's advantage is ads (none vs shown) and update cadence (every 6 days vs every 3 weeks). On price and device support there is nothing between them.
