Aquariums are among the most popular hobbies in the world. World-wide, keeping a fish tank is far more common than keeping a dog. It is far more common than playing soccer – and even more common than playing video games. Not just in the western world, but also in markets such as China or India, to protect, raise and care for life is an essential need in human beings…


The Game

Biotope is the most beautiful and most realistic aquarium simulator to date. The game combines photorealistic visuals and scientific simulation.

Players can setup multiple fresh water tanks from 20 up to 500 litres and raise their own population of fish and plants. The in game aquarium store offers everything needed to create and maintain a lifelike biotope. If players treat their pets as nature demands, they will be rewarded with newborn fish and flourishing plants. Own breedings can be sold to generate income, which players can invest to upkeep tanks, in new fish, hardware or accessories.

Biotope simulates fish and plant growth, water quality (pH, KH, temperature), stress levels for each fish, swarm behavior as well as mating/breeding behavior. Fish and plants both do have a full lifecycle from birth to death. Using the tanks editor, players can create the adequate environment for their lifeforms, feed them, treat sicknesses and consider fish constellations. Happy fish will reward players with new life, vivid colors and good health. The player must also keep an eye on their financials. With bigger tanks, new costs arise while income can be created selling breedings or winning competitions.



Biotope’s features a shop and a community market place offering everything necessary to setup and maintain various types of fish tanks, to feed, cure or just add fun accessoires to personalize the tanks. Players can also sell used items and their own breedings online. The Blue World shop features over 1000 items.


Aquarium Editor

The editor allows to setup and modify tanks. Players can be creative and build beautiful biotopes following their own designs, matching their taste and preferences.


Quests and Experience

Over time, players gather more and more experience and will eventually and gradually level up gaining access to new items, tanks and fish. New quests also become available. Advanced Players can become breeders, selling their fish (and plants?) to other players and that way generate (virtual?) income from the game.
