Alternanthera reineckii
Originates in southern Brazil and Paraguay, where it grows as a marsh plant with long-term water-holding adaptations. The easiest species to grow underwater is this one, as it is the most stable. A. reineckii has long been a stunning accent for ornamental aquariums. This alternanthera stays flooded for a considerable amount of time in the natural world.
The leaves are sessile, elongated-elliptical in shape, located crosswise (each subsequent pair is perpendicular to the previous one). Their length is 2.5–3.5 centimeters, width 0.5–1.5 cm. The upper side is green, the lower side is pink or red. In summer, tiny sessile yellow-green or pinkish flowers appear in the axils of the leaves. Underwater, the stem grows vertically and in in shallow aquariums it quickly comes out. Surface processes are used to further adapt the plant in ground conditions. If they are lowered under water again, the leaves will fall off. So the tops of the plant, located above the surface of the water, help preserve the species when the conditions of existence change.
Alternanthera reineckii is planted on the sides or in the middle of an aquarium. In the aquarium, Alternantera reineckii grows 10–15 cm per month.
The ideal aquarium to house the Rhinek alternator has the following water parameters: pH 6.2–6.8, temperature 24-28 C, stiffness 3-6. can transfer a 20-second drop in water temperature, but plant growth is slowed. High-quality water changes that are essential.
Bright lighting (~ 70 lm/l) is required for Alternanthera reineckii. The lighting in the aquarium has a direct impact on this plant’s appearance and leaf color. The length of the daylight hours varies and is determined by the strength of the light sources.
For novices, the primary issues with alternanthera are light imbalance, Redfield proportions with a margin, and other elements of a successful herbaceous life. Lack of lighting makes alternanthera appear like a pulled chicken. Beginners frequently lament that their alternanthera is covered in xenon due to over-lighting (green algae). Practice does matter in this situation. However, a herd of theodoxus snails or their more costly relatives, neretina, will aid in the resolution of xenon issues.
For Alteranthera reineckii, the soil’s nutritional value is not very significant. Most of the nutrients that the plant needs come directly from the water. As a substrate, coarse sand works well; alternanthera reineckii roots grow much more readily in it. During the plant’s rapid growth, feeding it with fertilizer tablets is very beneficial. Enough nitrogenous substances and microelements should be given to Alternanthera reineckii. Iron (such as iron gluconate) must be added to the water.
Alternatively, Tetra PlantaMin, a more stable chelate that includes iron, potassium, manganese, and other crucial microelements, could be used. Our only recommendation is to apply fertilizer once a month, which is a deviation from the manufacturer’s dosage recommendations. Instead of the other way around, divide the dosage and modify the fertilizer to your aquarium.

Alternantera reineckii is a vegetative breeder. Cuttings are taken from rather large stems that have four pairs of leaves, and the stems are then allowed to float at the water’s surface. The cuttings can be planted in the ground right away once they start to form roots.
Humid greenhouses are ideal for the growth of Alternantera reineckii. The plant needs bright lighting, moist, nutrient-rich soil, and an air temperature between 26 and 30 WITH for best growth. Alternanthera grows densely into brilliant purple thickets under such circumstances.
Bright and adaptable, alternanthera is a plant that looks great in any kind of aquarium. This plant, which is well-known for its vivid hues and diverse leaf forms, not only makes your tank look better, but it also contributes to the general wellbeing of the aquatic ecosystem. Alternanthera is a great option for novices and seasoned aquarists alike due to its versatility in lighting conditions and ability to grow in and out of the water. This article will discuss how to take care of Alternanthera, why it’s good for your aquarium, and how to keep it healthy.
Alternanter Sideriy (Alternanthera Sesilis)
With sufficient lighting of the aquarium? The upper side of the leaf is usually green, the lower is light green or pinkish. In moderate light-respectively olive-brown and purple-red. Unfortunately, this plant has a less intense red color than the other types of alternanter cultivates we have. It grows equally well, both in shaded places and in direct light. The well -formed parts of the stems should be planted in the aquarium, which have at least four pairs of leaves. This is the only type of genus that multiplies quite quickly under water, forming powerful bushes. Groups of 10-15 plants look most attractive. They are good to decorate the rear walls of aquariums. In large species aquariums, alternanthera groups are placed in the middle part in free places, where they form islands with an area of 20-30 square centimeters. Alternanthera sessilis is characterized by the fact that in the terrestrial form it has a dense, highly branched stem, and in conditions of low humidity – creeping. Seeds are small, whitish.
Alternanthera sessilis var. lilacina is found in warm regions of the entire globe. This plant adapts well to different forms of existence and can grow both underwater and on land. The color of the plants is very variable and depends on the cultivation conditions. Usually the upper side of the leaf is olive-green, the lower side is from dark red to purple. But sometimes there are forms in which the leaves on both sides are colored intensely red. In the middle zone, the plant can be successfully cultivated in the summer in open ground. To keep in an aquarium, this alternanthera must be grown in conditions of high air humidity (85-95 percent) of a tropical paludarium at a temperature of 20 to 30 C. Young shoots that have not yet bloomed, when planted under water, easily take root and rarely die. The plant is insensitive to the chemical composition of water, equally well tolerates both partial shade and excess light, the optimal pH of water is about 7. The main rule when growing this alternanthera is to create fairly stable conditions in the aquarium. It grows well in clean water without algae.
An above-water plant called Alternanthera sessilis var. rubra grows well in a humid paludarium. It grows very quickly; in 3–4 weeks, the stem with many leaves reaches a length of 15-20 centimeters. Just one-third of the underwater form’s branched, creeping stems that emerge above the surface of the water straighten out and start to branch strongly. They typically grow to a length of 50–60 centimeters. The opposite-facing leaves measure 3.5–5.0 cm in length and 0.8–1.7 cm in width. They are painted a ruby-red on both sides. Additionally, the stem is red.
When pressed down against a pebble, it readily takes root and produces a large number of white roots in place of a separate pair of leaves. Red or pink, fully sessile flowers emerge in the axils of opposing pairs of leaves. This plant, which originates from the tropics, blooms during the equinox, when there is twelve hours of daylight per day, corresponding to a tropical day. These plants are typically planted in groups of three or more shoots in an aquarium.
The center of the reservoir, where they are positioned in front of taller green and yellow-green plants, is the most ideal location. In approximately ten days, they establish roots underwater; however, their growth rate is slower than in a paludarium, and they only keep their attractive appearance for a period of two to six months. Plants should be replaced with new ones when the leaves start to fall. This requires having a second greenhouse, which you will use to grow new adult plants from cuttings. Diffuse lighting and the highest possible air humidity are needed for this. A. sessilis var. rubra requires slightly acidic water and bright lighting in an aquarium.
Amazingly gorgeous plants called alternanteras are used as accents in ornamental aquariums. They also look fantastic when planted in garden plots near open bodies of water, where you can combine aquatic and surface-dwelling forms to create compositions that are anchored in the sandy soil of the coast.
Any aquarium would benefit greatly from the addition of alternanthera, which enhances the underwater scenery with dynamic textures and brilliant colors. These plants can significantly improve the aesthetic appeal of your tank, whether you go for the subdued tones of Alternanthera lilacina or the vivid reds of Alternanthera reineckii. They are a favorite among aquarists who wish to create a gorgeous and vibrant aquarium environment because of their striking appearance.
The adaptability of Alternanthera is one of its main advantages. Though they can tolerate a variety of environments, these plants thrive in bright light and on a substrate that is high in nutrients. They are appropriate for both novice and seasoned hobbyists because they are also reasonably simple to maintain. In addition to keeping them looking their best, regular pruning and upkeep can help prevent overgrowth, which can be a common problem with quickly growing species.
The general health of your aquarium can also benefit greatly from the addition of Alternanthera. By supplying oxygen and absorbing excess nutrients, these plants aid in enhancing the quality of the water. Their roots can also help to stabilize the substrate, which helps to stop problems like the growth of algae. An aquatic ecosystem that is healthier and more balanced is facilitated by all of these elements.
In the end, Alternanthera is a great option for any aquarium setup because it provides both beauty and usefulness. You can have a vibrant and flourishing aquatic display that improves the overall appearance of your tank and promotes the health of its occupants by choosing the right species and giving it the care it needs.
