Hemianthus micrantemoids (Hemianthus micranthemoides) or mikrantemia micrantemoids, few-flowered (Micranthemium micranthemoides) is a freshwater long stem plant of the family Linderniaceae.
In nature, common in coastal zones of stagnant water bodies of Central America.
Adapted to the aquarium content. Maintain biological balance, saturate water with oxygen.
Grass is ideal for aquascaping.
Gentle leaves eat up herbivorous and omnivorous fish.
The soft stem strongly extends upward, grows to 300 mm, in verticils of 3-4 elliptical leaves with a pointed end, 3-6 x 1-2 mm. Petioles are not developed.
Typical spacing between whorls is 10 mm.
The abundance of side shoots. Cap pronounced, floating in the water column.
Color – bright, light green.
Chemianthus micrantemoids properties:
- It grows actively, up to 100 mm in 30 days. Without prejudice transfers haircut caps.
- The roots are poorly developed, spread along the soil of a dense substrate. Chemianthus tends to ascend with no fixation.
- When purging the aquarium with carbon dioxide and a standard (0.7 W fluorescent lamp per liter of water), it emits bubbly oxygen. What got the nickname “pearl grass hemianthus.”
- Mikrantemoides prone to algae fouling.
- Cap or green carpet – a refuge for fry and spawning fish from predators.
Not fixed due to constant growth and reproduction.
The young micrantemoids are confused with the cube hemianthus, a related species.
Hemianthus leaves of cube are smaller, color is darker, without sharpening. The distance between vertices is 2–4 mm. Height – 40–50 mm.
Forms a green cover on the ground. Mikrantemoids are marketed as a “rug”, which exacerbates errors.
Novice aquarists are confused with a similar lisimachia. In lisimachia leaves are larger and coarser, fewer shoots.
Hemianthus micranthemoides were erroneously attributed to the families of plantains, norichnikovyh.
There are subspecies with 2 and 3–4 leaves in a whorl. The former do not grow so quickly and are prone to stretching.
For curly trimming green caps are not suitable.
- Hemianthus cube.
- Micrograme is shady. In nature, it is found in the swamps of Central America. Rooted in the ground grows vertically up to 200-2500 mm. The span of the bush is 120–140 mm. And also it is fixed on snags, stones and just floats in the water column. Illumination – 0.7 W of a fluorescent lamp per liter of water 9–12 hours per day. Growth is active.
- Monte Carlo mikrantemum. It grows in flowing ponds of Argentina. Looks like a cubic hemianthus, but with a developed root system. Leaflets are largest, up to 4 mm. Illumination – 0.5 W fluorescent lamp per liter of water. It grows up to 100 mm. Forms at the bottom of the green cover.
Caring for hemianthus mikrantemoids is not a problem. The main thing – the observance of the desired acidity and purging with carbon dioxide (CO2).
Temperature: 22–26 ° C.
Acidity: pH 6–7.2. With increasing pH, nutrients are not absorbed by plants.
Chelate compounds of metals break up and pass into a form inaccessible to micrantemoids.
Stiffness is not regulated. It is determined by the present fish, aquarium plants of other species.
The main parameter for chemiantus is CO2 content in water. It is established by carbonate hardness kH and acidity.
Yellow highlighted high values, blue – low.
At pH 7 and kH 6 carbon dioxide content will be 19 mg / liter.
Shrimp will help to estimate the concentration of CO2. They are hiding from zones with a carbon dioxide content of 27–28 mg / l to plant thickets.
If swimming around the aquarium, increase the gas supply.
Ventilation is carried out with the help of expensive gas equipment.
There are “folk” ways to get CO2. In a plastic bottle, prepare the mash. For an aquarium of up to 150 liters, a 1.5 l bottle is suitable.
During fermentation, do not fill the container to the top, 2/3 is enough. For 1 liter of warm (30–40 ° C) water, add ½ cup of sugar, tablespoon of yeast and ½ teaspoon of soda.
The remaining ingredients – to taste. Trap in the aquarium.
One refueling lasts for 12–15 days.
Disadvantages: the impossibility of dosing and shutdown.
CO2 ventilation improves water quality. Plants, absorbing carbon dioxide, saturate the water with oxygen.
For a living aquarium, CO2 doesn’t matter if it is less than 35 mg / liter.
Carbon dioxide is effective for the prevention of fish diseases. It has a bactericidal action.
Mandatory filtering and weekly water change from ¼ volume. Without replacement, the growth of algae in the aquarium will take on disastrous dimensions.
Sandy substrate with a fraction of 2-3 mm due to the underdevelopment of the root system. Depth – from 40 mm at the front wall, from 60 mm – at the rear and side. Bias will facilitate cleaning from dirt.
As a fertilizer, add a few small lumps of clay to the soil.
The illumination intensity is standard, 40–60 lumens of light output per 1 liter of water. Use energy-saving and cold fluorescent and LED lights.
Color temperature – from 5000 K. Duration of daylight – 9–12. Longer can not: grow algae-parasites.
Chemianthus mikrantemoido tolerates a haircut painlessly. Growth does not slow down.
Leaf color does not reduce intensity. The undercut of the top shoot stimulates the appearance of lateral whorls. The density of the bush increases.
Trimming with sharp scissors.
Avoid high volume haircuts. It is fraught with a violation of biological balance.
Aquarium for the design is preferred traditional form: a rectangular parallelepiped. The optimal ratio of height and width – 1 / 2–1 / 3.
Uniform illumination form using fluorescent tubes, LED lights, remote LED spotlights.
If you plan to use mikrantemoides for a green carpet, before laying the stones and koryag provide a “glade”. Mowing the lawn will need to be weekly.
And it is better to form a green cover of the cube hemianthus. For perspective, choose angular stones.
The larger, the farther from the front surface.
For a designer aquarium internal filter is inappropriate. Focus on the external, with a capacity of 7–10 volumes of an aquarium per hour. Since an abundance of vegetation is planned, there is no need for biofiltration.
CO2 ventilation is effective. Air purge is optional.
Planted plants planted immediately, when you start the aquarium. Carpet is formed in the center.
Hemianthus mikrantemoides shrubs with a cap are used in the middle and background, on the sides.
An interesting result is the fixation of micrantemoids on snags. The openwork driftwood grows interspersed with whitish roots.
Fill the aquarium with separated water in 3–4 doses in 1.5–2 days. Live inhabitants start on reaching biological balance.
A couple of weeks. Start with shrimp.
The inhabitants of the aquarium is also an element of scenery. Look at medium-sized schooling fish with a bright color.
The same neons.
Start trimming when the stem reaches 100–120 mm in length. First pinch the tops.
Cut off the parts used to increase the density of the bush. Make a haircut after the formation of a dense cap.
Do not let the soil carpet grow beyond 30–40 mm. There is a risk of separation of plants from the substrate.
Divide the stem into 2-3 parts or separate the side shoot. Dig into the ground at 20–30 mm. Shank rooted.
Will grow and when fixing on the bark or stone.
Tender leaves will be eaten by herbivorous fish and mollusks. Of the mollusks, ampulyarias are particularly dangerous.
Omnivores gnaw foliage with a lack of vegetable feed. The exception is soma and fighting.
Dig up and eat the plant entirely, with roots.

And also incompatible with chemiantus mikrantemoides cichlids and barbs. Petsilievye, gourami are limited compatible.
Poor tolerated neighborhood with Vallisneria.
Diseases manifest when non-compliance with the recommended conditions.
The main enemy is algae. Particularly prone to infection with fiber and blue-green.
Appear at daylight from 11–12 hours, sunlight and in the absence of water changes.
Overfeeding of fish without cleaning food debris and excrement is dangerous. Overdose of fertilizers, lack of nitrates.
The excess content of ammonia and nitrite in the water (plants are not absorbed) stimulates the growth of algae.
Parasites entangle foliage. Prevent the entry of light, CO2 and nutrients.
In advanced cases cause the death of the plant.
- The thread appears in the entangling plants of greenish threads. Mechanically (tweezers, toothbrush) remove the parasite. Siphon the bottom, replace 1/3 third of the water. Or process algae with hydrogen peroxide from a syringe once a day. The maximum dose is 20 ml per 100 liters of capacity. It helps in 10-12 days.
- Blue-green algae – slimy foliage and peculiar smell. Use antibiotics, erythromycin (sold in pharmacies). Tablets crush. Substitute from 1/4 of the volume of water. Add medicine to the aquarium at the rate of 400 mg of active substance per 100 liters of water. The rest of the inhabitants in this concentration will not cause harm. After 24 hours, siphon the remnants of the algae and perform the substitution again.
From all types of algae helps complete isolation of the aquarium from the light for 72 hours. Turn on intensive air purge. During this time, no one except the parasites will die of hunger.
Replace water before and after photo isolation. Remove residues. Attention, it is important the complete exclusion of all types of lighting.
Otherwise, the algae are returned.
Lack of nitrogen or phosphorus causes yellowing, twisting of the leaves. Optimal concentrations: N – 0.01–0.02 mg / l (KNO3 is added), P – up to 0.001 mg / l (KH2PO4 is added).
Lack of potassium is expressed by yellowing of the edges of the foliage, stained. Normal content: 0.01–0.02 mg / l (application of K2SO4).
Effective introduction of purchased complex fertilizers with macro-and micronutrients. Contain compounds of metals, chelates.
Available in the form of solutions, powders, tablets.
- Chemianthus mikrantemoides grows poorly due to unacceptable acidity and lack of carbon dioxide.
- Insufficient light causes the plant to reach for the light source. Foliage becomes shallow, the distance between whorls increases.
A small rug with plants up to 50 mm long costs 280–300₽.
To combat algae, get a pair of Siamese algae. Effective, but adults rarely switch to delicate plants.
Hemianthus mikrantemoides – a fast-growing aquarium plant with a pleasantly bright–green color. Used in aquascaping.
Adapted to trimming to form a curly cap.
Prone to fouling algae. Sensitive to water acidity.
To achieve a professional needs CO2 ventilation.
