About the Game


BIOTOPE - Aquarium Simulator is the first and so far only photorealistic aquarium simulator. Biotopes make it possible to create populations of fish and plants and actively influence their entire life cycle.

Take on strategic challenges and manage the expansion and operation of the aquarium, with a limited budget. Cultivate, breed and trade fish and plants.

Biotopes realistically simulate chemical and biological parameters. Keep an eye on values such as temperature, pH, carbonate hardness, nitrates and ammonia so that your aquarium provides the perfect living conditions for your fish.

Use authentic equipment such as filter pumps and lamps to maintain your biotope and create ideal living conditions for your fish and plants.

Many decorative objects are at your disposal to create beautiful and unusual biotopes.

Depending on the quality and performance of the individual components, their durability and effects on the entire ecosystem of the aquarium will change.



  • Getting Started: Choose from three starter kits: Empty Tank (Tutorial), Amazon or Malawi Aquarium.
  • Household: Use your monthly budget and keep an eye on the statistics!
  • Shopping: Browse the Blue World Store.
  • The building blocks of life: Breed healthy and strong animals to maximize the DNA rating of your fish!
  • Stress reduction: Take care of your fish and keep their stress level low. A stressed fish gets sick quickly and will not reproduce.
  • Decorate your aquarium: Design your biotope according to the preferences and needs of your fish and they will thank you with good breeding values and offspring.
  • Complete quests and earn additional budget to expand your aquarium.
