Extra Large Sphere 23cm Black
Approx. 23 cm diameter · 20–25 shrimp · black gravel
The extra-large sphere is the most impressive model in the Black Line. Its generous size and deep black design make it an exceptional eye-catcher in living spaces, offices, or prestigious reception areas.
Inside, typically 20–25 small shrimp live together with algae and microorganisms in a finely tuned natural cycle. The black gravel creates an intense contrast and makes the shrimp and the delicate structures in the glass stand out beautifully.
Every eccosmo ecosystem is carefully assembled by hand in Germany. The individual design and the natural development of the living components make each system a unique one-of-a-kind piece.

As it is a living and hand-designed ecosystem, the shape and arrangement of the gorgonian, gravel distribution, shrimp coloration, and algae development may differ from the product images. These differences are part of the individual character of each system.
What's in the ecosystem?
Glass
The clear glass is also used for laboratory applications. It is as thin as possible and as stable as necessary. This creates a particularly light, clear, and elegant appearance.
Water
The brackish water is specially prepared for the ecosystems in our laboratory in Germany. Salts, minerals, and contained microorganisms are carefully adapted to the living conditions of the shrimp and the biological cycle.
Gravel
For many years, we have used specially selected artificial gravel. This can be hygienically prepared and is significantly lighter than natural gravel. The lower weight reduces stress during transport and thus contributes to safer shipping of the shrimp.
Shells
There are a few small shells in every ecosystem. They not only serve for decoration but also release minerals into the water over time.
Gorgonian
The branched coral in the glass is called gorgonian. To protect natural coral populations, we only use artificially produced gorgonians.
A suitable individual piece is selected and cut by hand from a larger gorgonian branch for each ecosystem. This gives each glass its own shape and structure.
The gorgonian serves as a sitting and climbing surface for the shrimp. Algae, biofilm, and microorganisms can also settle on its surface, which are part of the shrimp's natural food source.
Algae
The ecosystem contains different types of algae, including fine green filamentous algae and brown surface algae. Both do not necessarily have to be clearly visible at all times.
The algae use incident light for photosynthesis. In doing so, they produce oxygen and, together with the natural biofilm, form an important food source for the shrimp.
Microorganisms
Tiny bacteria and other microorganisms take on an important part of natural waste recycling. They process organic residues and return the contained nutrients to the biological cycle.
Some of the microorganisms also serve as food for the shrimp.
Shrimp
The shrimp are the small stars of the ecosystem. They feed on algae, biofilm, and microorganisms and move between gravel and gorgonian.
The number of shrimp is matched to the respective size of the system. In the extra-large sphere, there are typically 20–25 shrimp.
The biological cycle fundamentally exists independently of the shrimp. They use the existing natural processes and are the most visible living component of the small world.
Cleaning magnet
A small magnet is located inside the glass. With the external magnet included in the delivery, this can be carefully moved over the inside of the glass to remove visible deposits if necessary.
12-month shrimp guarantee
This model comes with a voluntary shrimp guarantee of 12 months from receipt.
The guarantee applies if all shrimp in the closed ecosystem have died within the guarantee period.
The full guarantee conditions can be found in the enclosed manual. The voluntary guarantee is in addition to your statutory defect rights and does not restrict them.
Scope of delivery
The scope of delivery includes:
- a fully prepared and sealed eccosmo ecosystem
- typically 20–25 live shrimp
- an internal magnet for glass cleaning
- a matching external magnet
- a detailed manual with care and warranty information
Shipping and delivery
The ecosystem is usually ready for dispatch within 1–2 working days.
Within Germany, the order usually arrives within 3–8 working days.
For deliveries to other EU countries, different shipping zones, shipping costs, and delivery conditions apply. Please refer to our detailed shipping information for this.
Since the ecosystem contains live shrimp, we consider the expected temperatures during shipping. In case of exceptional heat or severe frost, shipping may be delayed by a few days to protect the animals.
