Coral moss can not only be cultivated as an ornamental plant in a pot. It is also very popular as an aquarium plant. So that the moss does not swim around freely in the aquarium and possibly clog the filters, you should tie it up. What you have to consider when untying.

Coral moss does not form roots in the aquarium

Tie up coral moss in the aquarium

Coral moss is a popular plant in the aquarium because it is very easy to care for and does not grow too quickly. It can be used to create very nice hiding places for the aquarium inhabitants.

However, if the coral moss gets the upper hand, you must divide it before it overgrows the entire aquarium. You should then tie it up to keep the plant where you want it. Otherwise the moss will swim everywhere in the pool, cloud the water and, under unfavorable circumstances, get caught in the filter.

Before you can untie the coral moss, divide it. Scissors and knives are good for this. But you can also easily pull it apart. The individual pieces should not be too small so that they can be untied more easily.

What can coral moss be tied to?

Materials that are available as ornaments in the aquarium are very suitable for tying up:

  • stones
  • woods
  • root
  • ornaments

To tie it up, use twine that will not rot in water. Experienced aquarists rely on fishing line or plastic threads. There are also experts who stick the coral moss in bunches onto stones and wood.

Caring for coral moss properly

Coral moss in the aquarium hardly needs any care. Like all types of moss, it needs sufficient light to grow well.

Fertilization is usually not necessary. Occasional CO2 doses ensure that the coral moss retains its strong green color and grows more compactly.

If a dense carpet of coral moss is desired, place coral moss on the bottom and cover with a stainless steel screen. This keeps the moss down. It can grow out through the holes and over time forms a dense green area.


The coral moss owes its name to the delicate shoots that look very similar to those of corals. The shoots are no longer than three centimeters. It comes from Asia and was found there at a waterfall before it began its triumphal march into the world.
