The "moss ball," Cladophora spheroides, is a distinctive and fascinating addition to any aquarium. In contrast to most algae, which are generally considered an annoyance, Cladophora is valued for both its decorative qualities and its usefulness. These soft, green spheres give your tank a natural look and feel, and they are beneficial to fish and plants in different ways.
This algae forms thick, cushion-like mats in lakes and rivers where it grows naturally. It keeps the water in an aquarium clean by absorbing extra nutrients that could cause harmful algae to grow. Additionally, the Cladophora offers a surface on which advantageous bacteria can proliferate, facilitating the breakdown of waste and promoting a healthier aquatic environment.
Cladophora spheroides is a useful plant that can also be a lovely decorative element. Its eye-catching green hue and distinctive spherical form can improve the aquarium’s aesthetic appeal by bringing the underwater scenery to life. This algae can be an elegant and useful addition to your tank, regardless of your level of aquarist experience.

Distribution
Habitat: reservoirs in the Northern Hemisphere that are spread across Eurasia, from the Pacific to the Atlantic Ocean, and have cool water (higher than 22 degrees). Cladophora is typically found in Japan and Iceland on the bottom of rivers and lakes.
Although it is found in reservoirs with a moderate salinity level, it prefers fresh water. The balls can grow to a diameter of 30 cm and have a 200-year lifespan under ideal circumstances.
Cladophora follows the current, ensuring the plant’s ability to continue photosynthesis. The Japanese refer to it as "lake ghost" because of this characteristic.
Growing and care
One of the simplest aquarium plants to maintain, sphere algae is excellent for novices.
It filters a lot of water through itself and adds oxygen to it in addition to further purifying it.
All that is needed to maintain the cladophora’s aesthetic appeal is to keep an eye on the water’s parameters and clean the ball of debris.
Water parameters for ideal maintenance
Unfavorable conditions cause Aegagropila linnaei to disintegrate and lose its attractiveness rather than to die.
-
A comfortable temperature for cladophora is 18-20 degrees (not higher than 22).
-
The water should be soft, with a slightly acidic or neutral reaction – an alkaline environment and high hardness negatively affect the plant.
Regular filtration and at least 30% weekly water changes are recommended because, like most living aquarium inhabitants, cladophora is sensitive to pollution.
Lighting requirements
Cladophora aegagropila does not require bright lighting because it is a deep-water organism that thrives in natural conditions at least two meters down.
Three types of light sources work well: incandescent lamps, fluorescent lamps, and natural light.
The balls can be positioned in dim corners or beneath obstructions.
Oxygen bubbles build up inside the balls in bright light; in the evening, they float to the top, and in the morning, they descend to the bottom.
Periodically clearing debris from spherical cladophora is necessary. It only needs to be removed from the aquarium once a week, given a quick rinse under running water, and then placed back where it belongs. The spheres might wriggle, but they’ll straighten out eventually.
Soil requirements
Since the plant lacks a root system, the size, shape, and other properties of the soil are irrelevant. Cladophora floats freely in the aquarium or rests on the surface without adhering to the bottom.
Demanding of fertilizers
Furthermore, cladophora doesn’t need extra fertilizer. It is sufficient to keep the aquarium’s other inhabitants in the proper balance and to keep an eye on its two primary parameters, hardness and pH level.
Cladophora spheroides, commonly referred to as marimo moss balls, are a common addition to aquariums because of their distinctive look and low upkeep requirements. These algae provide a surface for good bacteria and absorb excess nutrients, which not only improve the aesthetics of the aquatic environment but also make it healthier. They are a great option for novices and seasoned aquarium keepers alike due to their robustness and gradual growth, which also provides an easy yet beautiful way to improve the aesthetics and equilibrium of any aquarium.
Reproduction
Chloroplasts are dormant inside the ball. They become active if the ball breaks apart, and eventually they transform into distinct spheres. It is best to purchase a new plant instead of propagating cladophora, as the entire process takes one to one and a half years.
If the sphere has broken apart, you can cut away the dead, blackened sections and leave the remaining portion; in time, it will split into individual plants.
When algae fragments detract from the aquarium’s aesthetic, they are separated into their own containers, where ideal conditions are established.
"Bad" cladophora
A filamentous alga goes by the same name as Cladophora’s "sister." All surfaces have tough, green threads that are hard to get rid of.
The control measures include mechanically removing the cladophora, brushing the aquarium and its decorations, treating them with hydrogen peroxide or other special preparations, and creating an environment that is not conducive to the growth of algae.
"Bad" cladophora dislikes hot weather and bright lights.
Compatibility with aquarium inhabitants
Most tropical fish cannot coexist with green balls because of their preference for cool water.
Shrimp and catfish are good companions for cladophora in an aquarium because they can hide or sit on top of the plant, but they can also damage it. Plecostomuses and goldfish are also unfavorable neighbors.
Some residents may get scared by the floating cladophora balls in the aquarium. When angelfish see Aegagropila linnaei, they become extremely stressed and may even perish from fear.
Cladophora in aquascaping
Cladophora balls allow you to compose any way you want. To keep them from moving, they are arranged haphazardly and occasionally affixed to the ground or positioned between plants that have no lower leaves. To make the spheres appear to float in space, you can suspend them from a clear fishing line.
George Farmer, a British aquascaper, creates unique design elements using cladophora. He chops the balls into pieces, attaches them to flat stones, driftwood, and other items with glue, or ties them with fishing line so they resemble moss.
Other aquascaping enthusiasts attach the plant to pieces of mesh and use it to create entire carpets, following his example.
Here’s a little life tip for aquascapers. You can place a bit of moss in between the Cladophora aegagropila pieces and the decorations. It will eventually grow to connect the object’s surface to the cladophora, allowing the fishing line to be removed.
In aquariums, Cladophora spheroides—which is frequently identified by its distinctive spherical form—offers benefits beyond aesthetics. This decorative algae enhances the aquatic environment’s health and balance in addition to adding a touch of natural beauty. It is a useful addition to any tank because of its capacity to absorb excess nutrients, which aids in maintaining clear water and preventing unwanted algae growth.
Cladophora spheroides is a great option for hobbyists who want to add visual appeal to their aquariums while maintaining a stable ecosystem. It can flourish in a variety of water conditions, is low maintenance, and is simple to care for. Furthermore, it can support beneficial microfauna, which helps maintain a healthy environment for fish and plants.
Adding Cladophora spheroides to your aquarium enhances its aesthetic appeal and helps create a more vibrant and well-balanced aquatic community. It is an exceptional option for anyone wishing to create a harmonious and colorful underwater world because of its unique blend of beauty and functionality.
