Hepatic mosses (monosolenium tenerum, riccia, hepatic) in an aquarium: reproduction, plant photo, content, description

Mosses or bryophytes are the oldest representatives of the plant kingdom and the sub-kingdoms of green plants. More than 6 thousand species belong to the class Hepatic mosses. In aquarium use riccia floating.

The monosolenium tenerum, known as pellia, is less common.

Monosolenium tenerum is a rare hepatic moss found in China, Thailand, India, and Japan in separate colonies.

Riccia is widespread in temperate countries of the northern hemisphere.

In species, there is much in common: both belong to the Marchancia order, their external characteristics are similar, as is the content and care for them.

The reproductive organs of anteridia (male) and archegonia (female) are arranged like leafy mosses. Liver mosses have a flat thallus (thallus) that floats on water. Thallus has a complex structure, consists of two tissues:

  • bottom (main);
  • top (assimilation).
  • On the underside of the underlying tissue are the epidermal cells, from which the rhizoids and abdominal scales emerge. Rhizoids are used to attach to surfaces.

    The lower tissue contains chloroplasts. In Riccia, there are air chambers in the assimilation tissue.

    Mossy form a hemisphere or pillow.

    Riccia consists of twigs 1 mm thick. It is much lighter than pellia in weight.

    Islands of floating floating are located at the surface of the water.

    The larger monosolenium, tenerum, has leaves up to 9 mm wide. Branched every 1.5-2 cm.

    The weight allows the liver moss to remain at the bottom.

    If the rhizoids are underdeveloped, fix the flora artificially with fishing line. The process of fixing is laborious: particles of bryophyte quickly disintegrate.

    Requires skill and accuracy.

    Monosolenium and Ricci require:

  • Bright light. In the dim light of the colony becomes rare and looks faded. With a strong shortage – the colony falls apart.
  • Liver cells survive at temperatures from -5 to 32 degrees. Feel comfortable at 22-29 degrees.
  • PH value –0–8.0.
  • Water hardness 2–21 dGH (medium to hard).
  • Regular replacement of a third of the volume of water.
  • Slight movement of water.
  • Large and herbivorous fish will severely damage the bryophyte. Place the liver moss in the tank with small omnivorous and carnivorous fish:

  • guppy;
  • mollies;
  • barbs;
  • cockerels;
  • rasborami.
  • Liver bryophyte reproduces sexually and vegetatively with the help of spores. Separate the piece from the common plant and deposit it in another vessel.

    Planted a piece of moss on a stone, snag, or other aquarium decoration. From the dispute soon formed new shoots. Provide the plant with enough carbon dioxide and light.

    Do not fix nets, fishing lines and stones, so as not to destroy the young leaves. In autumn, monosolenium tenerum forms brood buds.

    Branches at the ends of thalluses die off, new shoots appear from them.

    Liver mosses are of great benefit to an aquarium:

  • transform the reservoir;
  • provide mineral metabolism;
  • saturate the water with oxygen;
  • filter water;
  • create shade for shade-loving fish;
  • hide fry and shy fish;
  • create conditions for the construction of spawning nests;
  • They are a suitable breeding ground for ciliates, a component of the diet of most fish.
