Aquarium mosses are smart picks for keeping in planted tanks. They are the easiest aquarium plants to maintain. Mosses are almost impossible to kill (indeed, as plant keepers say), and surprisingly they can grow without any care.
Mosses bring visual appeal to an aquarium, and like all other plants, they are excellent natural filters. They provide a healthy aquarium condition with pristine water and supply additional snacks and shelter for your fish.
Java Moss and Christmas Moss are the most famous names from this family. People show their interest in reading a comparative study of Christmas Moss VS Java Moss.
I am keeping both of them in my home aquariums. Here I present a comparison of Java Moss VS Christmas Moss to make it easier for you to decide which one would be your first choice.
Christmas Moss VS Java Moss
I will discuss Java Moss and Christmas Moss separately, but I want to summarize their characteristics briefly before that. Both of them are very similar in appearance, but they are not the same. They have different needs.
Java Moss is very suitable for a low-tech aquarium. They are absolute ‘no complaining’ plants. They survive in a wide range of water conditions, require significantly less light to propagate and do well in a ‘no-care’ situation.
Christmas Moss, on the other hand, is a relatively higher light-demanding plant. Even the CO2 supplementation stimulates their growth and color. However, Christmas Moss tends to grow flat to cover rocks and driftwoods wherever you place it. People use them to create walls by placing the Moss between two mesh pieces, like a sandwich.
Java Moss (Taxiphyllum Barbieri) is native to Southeast Asia, and nowadays, a prevalent plant in the aquarium tend. Probably, Java Moss is the most popular aquarium plant from Mosses family.
Java Moss is straightforward to plant, grow and maintain. They can grow in any aquarium with a wide range of water conditions. You can grow Java Moss on rocks, gravels, driftwoods, or even keep them floating.
Java Moss does not demand much. They don’t require a lot of lights and care. At the same time, they grow without CO2 and fertilizer supplementation.
Java Moss has a stringy growth pattern and fills the aquarium with dark & vibrant greenery. As they are very versatile, the most widespread use of Java Moss is aquascaping to create a beautiful underwater garden.
Java Moss is also common in breeder tanks as they create ideal places for eggs and fry to hide. Besides shelter, they provide a perfect place to infusoria, the excellent first food of fry.
Java Moss Tank & Maintenance Requirements
Java Moss is a very hardy plant and survives in almost all conditions. Still, like all other plants, they have some optimum points. For example, Java Moss does their best in soft, slightly acidic water and temperature between 70 – 75 °F.
But to be frank, Java Moss is quite okay in temperatures between 60 – 85 °F. The wide variation of pH between 5.5 to 8.0 is perfectly suitable for them, and they can tolerate hardness up to 20 dGH.
Apart from trimming, no other maintenance is really essential for Java Moss. And trimming is solely your choice. You can let Java Moss grow wild or shape them in your particular preference.
Possible Problems With Java Moss
The most common problem with Java Moss is, it can get attacked by algae. Once algae grow deep into this plant, they are impossible to eliminate. The best solution for a severe algae attack is to remove the Moss and start again.
The second problem occurs if you don’t trim Java Moss regularly. Light and nutrients will not reach inner sections if they grow too dense, and plants may start turning brown and die. Sometimes, excessive growth of the Java Moss can occupy and clog the aquarium filter.
Christmas Moss (Vesicularia montagnei) is from the Moss family and grows in damp conditions in many places. They are native to Australia, China, India, Japan, Thailand, Srilanka, Sudan, and Vietnam.
The thicker and triangular-shaped leaves of Christmass Moss resemble the Christmas trees (you understand why they are named so.)
They are also trendy in aquarium husbandry. Christmas Moss is an excellent carpeting moss and is also famous for creating walls. They are very suitable to use with driftwoods and rocks, hence perfect for aquascaping.
Christmas Moss Tank & Maintenance Requirements
Unlike Java Moss, Christmas Moss is not such a low-demanding plant. They require moderate lighting for healthy growth, and their tolerance range is a bit narrow.
Christmas Moss does their best at a slightly warmer temperature. The optimum condition for Christmas Moss is 72 °F temperature and pH between 6 – 7.5. However, they are okay at 65 – 80°F and 5.5 – 8.0 pH.
Though CO2 and fertilizer supplementation is not mandatory, Christmas Moss thrives with accelerated growth with such feeding.
There are no particular maintenance requirements for Christmas Moss. But people use Christmass Moss in aquascaping, creating carpeting and wall effects. So you need to follow specific trimming methods to shape them as per your aesthetic preferences.
If you allow your Christmas Moss to grow wild, it will look almost similar to Java Moss in natural conditions. The only difference is, the Christmas Moss has fluffier leaves.
Possible Problems With Christmas Moss
The common problem is algae, with mosses particularly. So there is no specific problem associated with any particular species of mosses. But, as the situation is expected, the mitigation is also the same.
You will have to make a healthy water condition to get rid of algae attacks. Frequent trimming is an ideal practice to keep your Christmas Moss healthy.
