Fish Game

Fish Game is a freshwater fishkeeping simulation where you care for fish, plants and a custom-built aquarium. Fish have distinct personalities and behavioral quirks, and their evolving relationships can form complex hierarchies. You also manage water quality and create a habitat with sculptable substrate, rocks, driftwood and other decorations.

Fish and plants

The game includes over 130 types of fish, with behaviors such as schooling, chasing, fighting and carnivory. A hunger and food system covers herbivores, omnivores and carnivores, including grazers, opportunists and predators, with 11 types of food. You can also raise 50 species of aquatic plants.

Build your aquarium

Choose from over 50 types of rocks, driftwood and novelty hardscape, including setpieces from other games. Shape and layer 25 types of substrate in a range of colors. Fishkeeper XP unlocks content and mechanics, including tank upgrades from 7 to 3000 gallons and shop upgrades that offer rarer critters. Shopping has no currency economy or currency grinding; it focuses on discovering rare items.

Water and care

The aquarium models carbon dioxide, ammonia and oxygen, with relationships between these levels, fish, plants, algae and light. In No Death Mode, you can keep a living aquarium without deaths.

Photos and viewing

Photo Mode lets you take pictures and set up dolly shots to share with friends and enter community contests. Steam Link support lets you display an aquarium on a TV.
