📊 Eco Indicators

Oxygen 🫧 50%
40-80% optimal, too high or low is dangerous
pH Value ⚗️ 7.0
6.5-8.5 optimal, affects all organisms
Nutrients 🧂 50%
Plants need it, too much causes eutrophication
Toxins ☠️ 0%
Lower is better, above 50% is very dangerous

🎯 Game Objective

Create and maintain a stable micro-ecosystem where different organisms coexist harmoniously.

🎮 Basic Controls

  • Environment Control: Adjust light, temperature and ventilation to affect ecological balance
  • Add Organisms: Choose suitable organism combinations to build food chains
  • Monitor Indicators: Watch Oxygen, pH Value, Nutrients and Toxins

🌿 Organism Behavior

  • 🌱 Green Algae: Fixed swaying, performs photosynthesis
  • 🌿 Blue-Green Algae: Tiny floating, can fix nitrogen
  • 🍃 Duckweed: Surface drifting, provides shade
  • 🌾 Waterweed: Underwater swaying, purifies water
  • 🦐 Cherry Shrimp: Small hopping swim, cleans algae
  • 🐌 Apple Snail: Slow crawling, benthic cleaning
  • 🐟 Zebrafish: Natural swimming, actively foraging
  • 🦞 Crayfish: Alert swimming, top predator
  • 🦠 Nitrifying Bacteria: Micro-vibration, decomposes waste

⚖️ Ecological Balance

  • Food Chain: Ensure each trophic level has suitable numbers
  • Dissolved Oxygen: Produced by photosynthesis, consumed by respiration, needs to be moderate
  • Nutrient Cycle: Plants consume Nutrients, decomposers release Nutrients
  • Waste Treatment: Handle Toxins in time to avoid ecosystem collapse

🚨 Common Issues

  • Algae Bloom: Reduce light or add herbivores
  • Low Oxygen: Add plants or improve ventilation
  • Population Imbalance: Adjust predator and prey ratios
  • Water Quality Decline: Use emergency open bottle function

🎊 Achievement System

Complete specific goals to get achievements: maintaining balance, biodiversity, extreme survival, etc.

💡 Organism Behavior Observation Guide

🔄 Nutrient Cycle Mechanism

Sunlight Energy Flow: Light → Plant photosynthesis → Produces oxygen and organic matter

Food Chain Transfer: Plants → Herbivores → Carnivores

Matter Cycle: Dead organic matter → Decomposer decomposition → Releases Nutrients → Plants absorb

🎬 Organism Behavior Interpretation

  • 🌱 Green Algae Swaying: Fixed to substrate, gentle swaying indicates active photosynthesis
  • 🍃 Duckweed Drifting: Slowly drifts on water surface, provides shade and cooling
  • 🌾 Waterweed Swaying: Roots fixed, sways with water flow, purifies water quality
  • 🦐 Shrimp Hopping: Small hopping swim, indicates foraging for algae
  • 🐌 Snail Crawling: Slow deformable movement, cleans surface attachments
  • 🐟 Fish Swimming: Smooth swimming, activity reflects water quality status
  • 🦞 Crayfish Alert: Intermittent fast movement, top predator behavior
  • 🦠 Bacteria Vibration: Tiny vibration, decomposes organic matter and purifies water

🌡️ Environmental Factor Effects

  • Light: Strong light promotes plant swaying, weak light slows growth
  • Temperature: Suitable temperature makes organisms active, extreme temperatures slow behavior
  • Ventilation: Affects gas exchange, more bubbles when Open
  • Water Quality: Animals swim actively when dissolved oxygen is sufficient, slow when oxygen is low

⚠️ Abnormal Behavior Warning

  • Plant Swaying Slows: May lack light or nutrients
  • Animal Swimming Slows: May lack oxygen or water quality deteriorates
  • Organisms Gather in One Place: That area may be more suitable
  • Activity Completely Stops: Organism health is severely damaged

🎯 Observation Points

  • Rhythm Changes: Organism activity rhythm reflects environmental state
  • Spatial Distribution: Different organisms occupy suitable ecological niches
  • Interactions: Observe predator and prey relationships
  • Environmental Response: Observe organism reactions when adjusting parameters

📈 Success Indicators

Ideal state: various organism behaviors are natural and smooth, activity rhythm is stable, ecosystem operates harmoniously.
