Fish tank owners always look for the best plants to create a beautiful and lively aquarium environment. One famous favorite is the Bacopa australis aquarium plant, which is easy to grow. This bright green plant can float on the water’s surface or use roots to anchor it underwater.
Bacopa australis is best known for its emersed growth of stems above the water surface. This article will discuss Bacopa australis, its required conditions to grow, and how to develop a lovely spread of Bacopa australis in your planted aquarium.

What is Bacopa Australis and Its Family?
Bacopa australis, a member of the Plantaginaceae family, is commonly referred to as the “Southern Bacopa”. This water plant is native to South America, such as Brazil and Argentina. It is frequently located in slow-moving areas like rivers and streams. Moreover, this fish plant has oval-shaped shiny green leaves that stand out in the tank against darker greens or brightly colored fish.
In the right light, growth will spread horizontally, thus creating a green carpet look and an addition to the lighting of your tank. Also, the plant’s oxygen production helps to enhance the overall water quality and supports the welfare of aquatic life.
Lighting for Bacopa Australis Growth
Lighting is a significant factor in the optimal growth of Bacopa australis. This plant is fairly adaptable, but it is best in a middle-to-highlight environment. Here are some factors to look at the basic types of lighting needed for the growth of this plant.
- Light Intensity: Bacopa australis ought to be in a moderate to high light tank for maximum development. Specifically, you should be getting about 30–50 lumens per liter.
- Color Temperature: The light should have a color temperature to the natural light ranging between 6,500K to 8,000K. This particular color scheme will be alike to natural sunlight and helps most aquarium plants turn green.
- PAR Values: Photosynthetically Active Radiation (PAR) should range from 50 to 100 μmol for medium light and 100 to 150 μmol for high light. Higher PAR values will enhance the quicker growth but at the same time, there would be a frequent need for supplementation of CO2.
- Light Duration: They need to remain switched on for roughly 8 to 10 hours daily. But they should ensure that there is no over lighting because this leads to algae growth. It can also turn off and on at fixed intervals to ensure that plant light conditions are stable.
- Light Distribution: Make sure you have an equal light distribution over the tank. This ensures that a few carpet segments will grow faster than others, and they will be more exposed to it.
- During weak light, the plant grows upright in an attempt to reach the light instead of expanding sideways.

Bacopa Australis Emersed
As realized that Bacopa australis aquarium plant grows well emersed, or above water. So it is a good practice to first grow this plant out of the aquarium before putting it into the tank. To cultivate Bacopa australis above the water, you’ll need to pay attention:
- Temperature: The plant is adaptable to humidity, but it grows best in temperatures between 20C to 28C or 68F to 82F. During emersed growth conditions, the temperature should be geared slightly towards the higher side of the scale, ranging from 24℃ to 28℃.
- Water Parameters: Further, the plant grows best in slightly acidic with a pH level ranging between 6 and 7.5. Soft water is preferred for this plant; however, they are favorable to grow it in slightly hard water.
- Humidity: Because Bacopa australis is generally cultivated in emersed conditions, it is necessary to maintain high levels of humidity. It may be necessary to have a structure that has several compartments like a greenhouse.
- Lighting: In the case of growing this plant emersed, lighting can be considered moderate to high. It is recommended that the PAR should range from 50-100 μmol/m²/s and the color temperature to be around 6500K for emersed growth.
In its emersed form, Bacopa australis is capable of producing small flowers which gives it beauty.

Make a Bacopa Australis Carpet in a Fish Tank
Making a Bacopa australis carpet can make an impossible dream come true, to turn your aquarium into a green paradise. Thus, the plant’s ability to creep makes it perfect for a carpet-like application, but some factors would have to be looked at.
Substrate: The growth of Bacopa australis aquarium plant requires a nutrient content in the substrate. A combination of plants such as aquarium soil or root tabs is preferable to provide other nutrients like Nitrogen, phosphorus, and potassium to the plant.
CO2: Growing Bacopa australis without CO2 is not a bad experience for the roots. But when CO2 was added, a faster and healthier growth of the carpet was noted. The recommended concentration of CO2 for optimum growth is about 20-30 ppm. Under high-technology systems utilizing CO2, Bacopa australis growth could be very rapid and dense.
Planting Technique: Plant Bacopa australis carpet by using small plant cuttings and planting them separately in the substrate. Make sure to plant them in rows, approximately 1 to 2 inches apart to allow the plants to spread horizontally. Prune the plant frequently so that it grows flat on the ground instead of leaning upwards.
Water Flow: It is preferable to maintain a moderate water flow as it is suitable for the Bacopa australis aquarium plant. Tidal currents may uproot the plant or hinder its growth in some areas more than others. Make sure that the water flow is not so powerful that the plant cannot set its roots. But at the same time, there is enough powerful airflow for the nutrients to circulate.

Bacopa Australis Care
Aquarium plant Bacopa australis is relatively low-maintenance once established but does require consistent care for optimal growth:
- Trimming: Trimming is necessary and should be done often to keep a carpet healthy. The trimmings can be used to propagate other plants or to replace loose patches on your aquarium carpet.
- Water Changes: The water should be changed at least once a week, it is recommended to change about 20-30% to keep the water clear and to control algae. This is important if the system incorporates high light intensity with the CO2 injections as conditions favor algae growth.
- Fertilization: Bacopa australis will have to be fertilized regularly in high light and CO2 environments. Fertilizing the plants with a balanced liquid fertilizer containing macronutrients and micronutrients should be done frequently. This process ensures that the plants can grow healthy.
- Algae Control: The aquarium plant Bacopa australis is very prone to algae, especially in high-lighting conditions. Add a few algae-eating fish like Amano shrimp or Otocinclus that are naturally big on algae.
Closing Remarks
Bacopa australis is a quite flexible and attractive plant for people interested in having an emersed plant in an aquarium. Thus, this plant can grow perfectly well under moderate to highlight intensity, with additional CO2 supplementation, and regular trimming. For the beginner or experienced aquatic gardener, the Bacopa australis aquarium plant presents an opportunity to produce a carpet that complements the inherent beauty of the aquarium.
When you follow the steps explained above, you will be able to properly cultivate Bacopa australis and turn your fish tank into an aquatic paradise.
