Staurogyne Repens Carpet Care Guide – Carpet, Floating, Propagation

Staurogyne repens carpet is among the most popular freshwater plants belonging to the Acanthaceae family, with over 2500 species worldwide. The Cristalino River, located in South America, is home to this species. It’s a tough plant that can withstand many of the mistakes that new fishkeepers make. As a result, it’s appropriate for anyone wishing to incorporate some vegetation into their aquarium.

Staurogyne repens, like all plants, will improve the quality of the aquarium’s water, assisting you in keeping your tank clean. As it photosynthesizes, it will release oxygen and eliminate some of the nitrate and toxins present in the water. The brilliant green colors and bushy appearance distinguish this plant from others; it’s a popular option in aqua-scaped tanks.

Staurogyne Repens Carpet Overview

Staurogyne repens is a multipurpose aquarium plant belonging to the Acanthaceae family of the dicotyledonous floating plants, with approximately 2500 species and 250 genera. The Staurogyne genus has six freshwater species, the most common of which is Staurogyne repens, which is well-known for its usage in freshwater aquarium decoration. In the South Amazonas, the River Rio Cristalino situated in Mato Grosso is the source of this freshwater plant species. On the banks of the fast-flowing river, the little plant grows on and between hardscapes (rocks).

Staurogyne Repens Carpet Appearance

Staurogyne repens resembles species of the invasive Hygrophila genus, which includes South American marsh weeds, but it is taller and has larger leaves. It has a vivid green color, brighter than other hardy forms such as hornwort.

The stems are rigid to keep them in place in the tank. Their leaves are lively and densely packed, making them perfect for creating a carpet on top of the substrate.

This carpet will grow about 2-4 inches tall, giving you lots of open swimming space beyond a mature plant.

The leaves themselves have a pretty classic leaf shape, being an oval with a broad base and a tip at the end. The roots are white and slender. They’ll generally get buried in the substrate to keep the plant in place, although they’ll occasionally sprout upwards (to gather nutrients from the water).

Staurogyne Repens Carpet Size

The typical Staurogyne Repens Carpet typically grows up to 4 inches. Staurogyne repens have a distinctive appearance that makes it ideal for aquascaping (an excellent foreground plant). It forms a lovely thick carpet that can grow four inches tall. This means that, despite covering the substrate, it won’t take up too much room in your tank. The color is one of the favorite aspects of this plant. The green is fairly vibrant, and it can drastically alter the color dynamic of the aquarium.

Staurogyne Repens Carpet Care and Tank Set-Up

You must create an environment that closely resembles Staurogyne Repens’ natural habitat for it to thrive in your aquarium. You must keep the following requirements in mind to do so.

Staurogyne Repens Carpet Tank Size and Specifications

Optimum Tank Size for Staurogyne Repens Carpet

The recommended tank size for Staurogyne Repens Carpet is 10 gallons.

Staurogyne repens’ only drawback is that it needs very precise water conditions to grow, which is why it is only found in a few places of South America. As a result, you’ll need to make the Rio Cristalino as realistic as possible in your aquarium to offer the plant the best possible chance of thriving.

The Staurogyne plant requires a tank with a minimum capacity of 10 gallons to thrive. The plant is best utilized as a foreground specimen in small aquariums. Still, it may be used to great advantage in bigger tanks to form a carpet that stretches across the entire aquarium’s bottom.


The plant requires a nutrient-rich substrate, combining tiny pebbles and aquarium soil or just aquarium soil. Remember that fine-grained aquarium materials assist Staurogyne repens’ small roots in penetrating easily and providing better anchoring. These substrates are high in nutrients and allow Staurogyne repens’ thin roots to penetrate easily.

Lighting for Staurogyne Repens Carpet Tanks

To flourish in the aquarium, Staurogyne repens require intense illumination; hence medium to high lighting (30–50 PAR) should be provided. The plant begins to grow upwards in low-light situations as if it is striving to access the surface for more light.

Sustain a photoperiod of a maximum of 10 hours each day; leaving the lights on for prolonged periods will cause undesired algae to bloom in the aquarium. A full spectrum LED lighting fixture might be employed to provide the desired light intensity.

Nitrogen/other nutrient requirements for Staurogyne Repens Carpet tank?

Staurogyne repens is a robust and vital plant that thrives in medium to high light conditions with CO2 supplementation. Fertilization is also required for Staurogyne repens. To preserve the fresh green colors of the leaves and constant covering growth, a combination of a nutrient-rich substrate and a supply of micronutrients is required. If the vertical branches were clipped before planting, it could be months before they need to be trimmed again. New vertical shoots may well be trimmed every week at that time.

Staurogyne repens, in addition to being a great foreground flora for the planted tank, is also an ideal choice for nano aquaria due to its slow, creeping growth and hardiness.

Staurogyne Repens Care and Maintenance

When it comes to caring for this resilient plant, there isn’t much to do; its small size and moderate growth pattern make upkeep simple. You won’t have to clip the shoots as often because the plant doesn’t grow quickly. In any case, if the carpet becomes too high or you discover regions that are significantly higher than others, trim the carpet to keep it level, neat, and compact.

Staurogyne Repens Care and Maintenance

Although Staurogyne repens is commonly referred to as a carpet plant, it is not one. Staurogyne repens is a non-carpeting stem plant. By clipping and replanting the cuttings, we may achieve the carpet appearance. You may also use this time to snip rotting leaves and stems; the goal is to separate the browns from the greens in your aquarium to create a homogeneous and appealing carpet.

Also, make sure to replace the water regularly to keep it clean and clear. Clearwater in the tank will aid in the penetration of light to the plants on the lower levels, including your Staurogyne carpet.

Dose liquid supplements in the proper amounts into the tank water to guarantee that the plants get enough necessary nutrients. This will go a long way toward fostering healthy roots and shoot growth, so if you want to keep your carpet looking fresh, dense, and bright green, you should incorporate this method into your routine.

Propagation of the Staurogyne repens

Staurogyne repens plantation process is not difficult; nevertheless, to get the desired quantity and quality of the foreground vegetation in the aquarium, one must follow a precise planting guideline.

According to certain aquarists, we should plant one stem for every two gallons (8L) of water to avoid overcrowding. However, it is preferable to keep a distance of roughly 2 to 3 inches (5 to 7 cm) between each other at first. It will lessen competition early on and allow them to establish themselves. Into the substrate, bury every stem about 12 to 34 of an inch (1.5 to 2 cm) deep. When planted this way, the thin roots will easily penetrate the aquarium substrate. Tweezers can be used to insert separate plants into the substrate.

Check the growth after 3-4 weeks to see if any large gaps need to be closed. If so, add a few additional stems. To encourage horizontal development, use liquid fertilizers and maintain the shoots trimmed from time to time. If you do have floating plants in the tank, make sure the water surface is clean enough for light to reach the carpet. After a few months, if these events are effectively executed, the desired carpeting effect will be accomplished. In terms of propagation, Staurogyne repens can produce vegetative buds, which is more common in its emergent phase.

Side shoots arise from the parent plant; these sections detach and fall to the ground, where they grow and develop into separate plants. However, mature stems can be readily clipped and replanted in the aquarium in the substrate. You don’t have to remove the entire stem; simply cut a 2-inch (5 cm) piece and set it in the substrate. The plants will develop and grow into a new plant even if there are no visible roots; it’s that easy.

Small Buying Guide

This species is widely available at local fish markets; if you can’t get it there, look online since several internet dealers sell it. You should avoid getting sick or damaged plants because they won’t grow properly in the tank. Healthy stems are often fresh, upright, and green or slightly brown. For $5-$10, you can get a large bunch with up to 10 stems, which should be plenty to aquascape a 10 to 20-gallon fish tank.

If required, quarantine Staurogyne repens before introducing it to your tank. For instance, if these are “in vitro” plants, there is no necessity to do so because they are grown on nutritional media under sterile laboratory conditions. In all other situations:

The plant may be infected with parasites, pests such as snails, or even predators (damselfly nymphs, dragonflies, etc.). To get rid of parasites, snails, and other pests, it could be treated with chemicals (pesticide). Fish, shrimp, and other invertebrates, on the other hand, are exceedingly poisonous to these compounds.

Staurogyne repens, according to the study, is tough enough to withstand a high concentration of H2O2 (hydrogen peroxide). Furthermore, explants treated with 5.5 percent H2O2 for 20 minutes produced the highest effects.
