Marimo Moss Ball Benefits
If you are like most people you probably think moss balls will make a nice looking addition to your aquarium, but you might wonder are moss balls good for aquariums. For the most part, moss balls provide most of the benefits of keeping live plants, like enhancing water quality and increasing oxygenation. The only downside to moss balls is that they tend to grow slowly, so they are not as effective as more common aquatic plant species.
Since moss balls require nitrogen to grow, they can help reduce algae blooms by out-competing the algae for nutrients. If you add a bunch of moss balls to your tank they will consume any excess ammonia and nitrates produced by your fish, so they won’t build up to high enough levels in your tank for algae to feed on.
Like most photosynthetic plants moss balls will emit oxygen as they process carbon dioxide into carbohydrates. As long as your moss balls are exposed to a sufficient amount of light they will help increase the total dissolved oxygen in your water.
Moss balls are favorite plants for a number of species like shrimp and Betta Fish. They make a fun toy for a Betta to roll around like a beach ball, which can help prevent them from getting bored in their small aquariums. Shrimp also love them since they like to feed on the algae and detritus the builds up on their surface. They can also be kept in tanks with snails since most snails won’t eat the moss, but they will help clean the moss balls surface.
Can You Have too Many Marimo Moss Balls?
There are actually some limits to how many moss balls you can actually physically fit in an aquarium. The main limit you need to be concerned with is light. If you put too many moss balls in a tank they can shade each other, which can cause some of the moss balls to die or turn brown in color.
You also don’t want to add too many moss balls to a tank since there might not be enough nutrients in the water for them to grow properly. This is usually not a problem if there are fish in the tank, but it is another point to consider if you have and understocked, or fishless aquarium.
Another thing you want to keep in mind is the comfort and safety of your fish. If you add too many moss balls they won’t have any room to swim, which can be just as bad as keeping them in a small aquarium.
Then there is the subjective matter of taste. If you add too many moss balls to a tank it will make the overall aquascape look unattractive and cluttered.
You also have to consider that the moss balls will grow and take up space, which will limit your ability to add anything new to your aquarium. As with anything just use some common sense, and if you do that you will most likely end up with a reasonable amount of moss balls in your aquarium.
