Aquarium species sagittarii, dwarf plant form

Sagittaria is a common aquarium hydrofit of the Chastukhov family. Sagittaria is translated from Latin as an arrow. For the appearance of the leaves in the people received the name arrowhead.

Perennial culture is not demanding to the conditions, it is well acclimatized, has many species. It is possible to place a plant both on foreground, and on a background, thanks to it the plant enjoys popularity.

Sagittarius is the most popular type as it is not demanding to the conditions and is well acclimatized.

In its natural environment, sagittaria grows on the banks of freshwater bodies and in shallow water. The area – the southern territory of North America, there are more than 30 species of plants.

In aquarium conditions, about 10 species can grow, they have similar conditions of maintenance, but they are radically different in shape and size.

About 10 sagittarius varieties can grow in aquarium conditions.

The general morphology of the arrowhead is as follows:

  1. The root system is tuberous. Short white roots are woven into knots, have a fragile structure.
  2. The leaves are narrow green and fleshy, petioles are possible, the plate is located on the surface of the water. Their number depends on the depth of placement of the plant. Terrestrial species are characterized by egg-shaped and heart-shaped sheet plate.
  3. Flowers – white, clustered in racemes.

Aquarists for decorative properties and accessibility prefer several types of sagittarii. The most popular ones are dwarf, sprawling, styloid and stiff-leaved.

Sagittaria spec appeared on the territory of Russia in the 80s of the last century, brought it from Holland. And the birthplace of the plant – Colombia and North America. Differs in small parameters, reaches 10 cm in height, sheet width – about 5 mm.

The dwarf sagittar develops well even in hard and acidic water.

Sagittary dwarf reaches 10 cm in height

For growth it is important to provide her with the following conditions:

  • water temperature – 18−28 degrees, capable of withstanding a long decline to 12 degrees heat;
  • the liquid must be clear, for this a good filter is necessary (turbid water leads to the formation of plaque on the leaves and their destruction);
  • weekly should be changed to ¼ volume of the aquarium, sludge is removed using a funnel;
  • illumination is moderate, if necessary, lighting is needed, because when there is a lack of light, the bush is drawn out and thins;
  • the ground is fine silted sand, the layer should be about 3 cm.

The advantage of the species is that it can be diluted in aquariums of any size. Grow dwarf form capable of both fully and partially under water.

It looks good gidrofit, if massively put it to the fore.

This species is the most popular in aquarium. It was found in the freshwater bodies of North America, and gradually spread to the South American continent. The styloid sagittrium has ribbon-like leaves, they can grow up to 90 cm from the socket.

The color scheme of the sheet plate consists of green and green-brown tones. Differs in ability to blossom in the closed space if it is located shallowly under water.

Inflorescences consist of 3 flowers. There are several varieties:

  • Subulata has 2 forms: Natans – the length of the leaf is 30 cm, and the width is 6 mm, and Pusilla – the leaf grows to 10−12 cm;
  • Kurtziana – leaf plate has a length of 30−90 cm and a width of 7−14 mm;
  • Gracillima – the leaf grows 30−90 cm in height with a width of 3-5 mm.

The arrowhead styloid most popular in aquarium

A characteristic feature of the sagittarius subulate is the dropping of leaves during transplantation, but after adaptation they grow back. For the full growth of the variety requires the following regime:

  • the optimum temperature is 20−26 degrees, any level of acidity is suitable;
  • good water filtration is necessary so that there is no souring on the leaves;
  • light – direct sunlight for 3−4 hours, the plant should be lit at least 12 hours, requires additional lighting;
  • the soil is nutritious, in the form of small pebbles or coarse sand, clay or peat can be placed under the roots for better rooting.

The advantage of the species is that the plant is able to quickly form a lush bush and is well rooted in the substrate, can grow in the aquaterrarium. Reproduction Sagittaria Subulata is happening rapidly, for 1 year can form about 100 lateral basal shoots.

Sagittarius with hard leaves is common in South America. It is distinguished by bright green short leaflets pointed form with a wide base.

They have a dense fleshy structure, due to which the species got its name. Mature plant reaches 20 cm in height and has a developed root system.

The hard-leaved arrowhead develops poorly next to other plants, so it should be placed separately.

Sagittarius with hard leaves spread over South America

The motherland of the species is the wetland of the Mississippi River; it can also be found in Asia and America. This decorative look is also known under the names of Japanese or platifilla.

Rosette bush consists of long dense ribbon-like leaves in the amount of 8−12 pieces. On the green leaf plate are pronounced veins in the form of a grid.

The plant reaches an impressive size, the bush grows up to 40 cm, and the leaves – up to 20 cm with a width of 4 cm. Flowering is rare, but lasts about 3 weeks. On a long peduncle white flowers bloom (up to 20 pieces on one brush).

Differs in slow growth – about 4 sheets per month.

The spreading or broadleaf form of sagittary is slow

For sprawling sagittarii need the following conditions:

  • temperature – 19−26 degrees;
  • acidity is neutral;
  • water hardness is medium;
  • the light is of medium intensity with a duration of 10−12 hours per day, with its excess, surface leaves are formed, and if there is a shortage, the plant turns pale and stretches;
  • soil – nutritious from small gravel or pebbles, sand.

When planting, it is necessary to fix the hydrophyte well on the bottom, as it can float to the surface. This is due to the content in the leaf tissue of the air intercellular spaces.

Additionally, you can flatten the roots with stones or wire pins.

It is preferable to place the Japanese woman on an elevation, as with its full immersion in water its growth slows down. And also the bush ceases to grow in close proximity with other plants.

The Japanese woman can reproduce in an aquarium only under good conditions, but after a transplant, quickly adapts to a new place.

There is no need to collect seeds for breeding, since sagittary multiplies vegetatively quickly. Formed individuals throw away shoots in the form of whiskers, on which rosettes of daughter plants are formed. After the formation of 4−5 leaves the plant can be separated and moved to a permanent place.

Many species are able in a short time to form a green carpet at the bottom of the aquarium, so you need to regularly prune and form the bush.

Arrowheads are found in shallow water, on the banks of freshwater rivers, lakes and ponds.

For the successful cultivation of culture should adhere to these recommendations:

  • the light should come only from above, since the bush is deformed during side illumination;
  • need regular mineral fertilization, its amount is 1.5−2 g per 100 l of water, pale leaves – a sign of iron deficiency;
  • carbon dioxide stimulates growth, it is needed in low light;
  • transplantation must be performed carefully, without deepening the neck of the plant;
  • all species require well-purified clear water;
  • the aquarium should be maximally populated by the inhabitants, but fish digging should be avoided.

Aquarium sagittar is a plant that is ideal for beginners. Simple care and a variety of beautiful views will allow you to create a unique underwater composition.
