Java moss comes from the island of Java and other Southeast Asian countries. The assumption arises that it consequently likes warm water. Is this right? Or is this plant tougher than we give it credit for?

Java moss can cope with a wide range of temperatures

living environment water

In this country, java moss is mostly cultivated in aquariums. Unlike in the wild and in a terrarium, it is completely surrounded by water. This element therefore has a decisive influence on his
Growth. Since water can have different temperature values, the question arises: How warm should it be for the java fern?

ideal temperature

It can be observed that the java moss grows fastest and most beautifully when the water in the aquarium is around 24 °C. Provided, of course, that it also receives optimal care and is well lit.

Large tolerance range

What happens to the java moss if the water in the aquarium is colder or warmer than 24 °C? Nothing to worry us about. Because the java moss is surprisingly tolerant of deviations.

  • Temperature fluctuations are accepted
  • Water shouldn't be too warm
  • Survival range is between 15 and 30 °C

Some providers even state the temperature range as 12 to 34 °C. But don't push your luck too much. It's not just about the java moss staying alive. Every crop deserves good living conditions. And of course we also want to see a healthy, well-growing java moss in the aquarium.

select temperature

Java moss only grows in hardly any aquarium. Usually other growths are also part of the party. There are also fish, shrimp and other aquatic animals. The water temperature must satisfy all aquarium inhabitants. Since the java moss is less sensitive in this regard than many other aquatic plants, it will have to be content with "foreign" ideal values.

Other water qualities

The java moss is also an adaptable plant in terms of water quality. The water in the aquarium can be slightly acidic or neutral, with a pH of 5 to 8. It grows in fresh water, but it also survives in brackish water.

The temperature values listed above also apply in the terrarium, although the air should also be humid.
