Plan your next Fish Game session
Our independent guide walks you through the documented systems of Fish Game—fish behavior, plant growth, tank scaling, chemistry, and visual sharing—so you can build balanced aquariums while understanding how each element influences the next.
01 / THE GUIDE
Compare Social Hierarchies
Select two fish with contrasting personalities and observe how their interactions shape the hierarchy. Note schooling or fighting patterns and relate them to the number of individuals present.
- 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
Plant Growth Rate Test
Plant a fast‑growing species alongside a slower one. Record growth over several in‑game days, then compare how each affects CO₂ and oxygen levels.
- Start with fast‑growing species to see visual changes quickly.
- Monitor CO₂ levels when adding many plants to maintain balance.

03 / THE GUIDE
Tank Size Impact
Upgrade from a 7‑gallon to a larger tank and add the same fish school. Observe changes in space usage, hierarchy stability, and substrate layering needs.
- 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
Water Parameter Balancing
Introduce a new predator and monitor ammonia spikes. Adjust lighting and plant count to restore balance, noting how each parameter reacts.
- Keep an eye on ammonia spikes after adding new fish.
- Adjust lighting to support plant photosynthesis while managing oxygen.
05 / THE GUIDE
Photo Mode Composition
Create a dolly shot that moves from foreground rocks to background plants. Compare the visual impact with a static shot, focusing on depth cues and fish placement.
- Use the dolly shot feature to highlight depth and plant layers.
- Enter community contests to see how others frame similar setups.
