About Fish Game
Fish Game is a freshwater fish‑keeping simulation built for hobbyists. It offers over 130 fish species, each with distinct personalities that create evolving social hierarchies, plus a detailed water‑quality model and plant growth system.
The title runs on Windows, supports Steam Cloud, family sharing, and can be streamed to a TV via Steam Link. It also works on the Steam Deck and includes a relaxing “No Death Mode” and a Photo Mode for sharing aquarium snapshots.
01 / THE GUIDE
Fish Personalities and Behaviors
More than 130 fish types each carry unique personalities and behavioral quirks. Interactions such as schooling, chasing, fighting, and carnivorous actions generate dynamic hierarchies that shift as new fish are added.
A comprehensive hunger system supports herbivores, omnivores, and predators with eleven food types, allowing each fish to act according to its dietary niche while influencing social dynamics.
- Watch early interactions to anticipate which fish may dominate the hierarchy.
- Match food types to dietary groups to keep fish healthy and reduce conflict.
02 / THE GUIDE
Aquatic Plant Propagation
The game provides fifty plant species that can be propagated and raised, adding visual depth and influencing water parameters as they grow.
Plant growth interacts with simulated carbon dioxide and oxygen levels, affecting overall tank health and giving players another layer of ecosystem management.
- Start with fast‑growing species to see visual changes quickly.
- Monitor CO₂ levels when adding many plants to maintain balance.

Tank Size and Upgrade Path
Tanks can be expanded from a modest 7‑gallon setup to massive 3000‑gallon habitats, offering space for more elaborate décor, while shops can be upgraded for rarer critters.
Larger tanks accommodate additional substrate types, rocks, driftwood, and novelty hardscape, letting players recreate elaborate aquascapes from favorite games.
- Plan substrate layers before expanding to avoid re‑arranging later.
- Use larger tanks to introduce species that need more space, such as schooling fish.
04 / THE GUIDE
Simulated Water Chemistry
Carbon dioxide, ammonia, and oxygen levels are simulated and interlinked with fish, plants, algae, and lighting, influencing fish health and plant growth.
Future updates promise advanced water chemistry and equipment, indicating ongoing depth to the system.
- Keep an eye on ammonia spikes after adding new fish.
- Adjust lighting to support plant photosynthesis while managing oxygen.
05 / THE GUIDE
Photo Mode and Community Sharing
Photo Mode lets players capture images and set up dolly shots, encouraging creative presentation of their aquariums.
Captured photos can be shared in community contests, and the game can also stream a living aquarium to a TV via Steam Link.
- Use the dolly shot feature to highlight depth and plant layers.
- Enter community contests to see how others frame similar setups.
