Moneywort Facts

One interesting fact about Bacopa monnieri is that it can produce small white fruits that contain many of its essential nutrients.

These fruits are also a great source of food for small animals such as copepods, aquatic insects, and small fish fry.

Additionally, this plant is known to improve water clarity by making nitrogen available to the roots, filtering out pollutants, and stabilizing pH levels.


This aquatic herb has small, fleshy leaves that are generally about 1 cm wide and 2 cm long.

The stems are delicate and can reach up to 10 cm in height with reddish stems and small, white flowers.

This plant has a shallow, but well-networked root system with numerous densely placed lateral roots. 


Bacopa monnieri is a native of India and Sri Lanka, but it can now be found in many other parts of the world including the United States.

This plant generally prefers slow-moving, nutrient-rich waters and is typically found in ponds, swamps, and other shallow waters.

pH Preference

The preferred pH range of Bacopa monnieri is 6.6 to 7.6, but it can tolerate pH levels outside of this range.

Its ability to oxygenate its environment helps provide an ideal pH range for a range of other species living in the aquarium.

Vivarium Type

Moneywort is quite an easy-going species. With that in mind, it will not be too complicated when it comes to choosing the type of enclosure it is grown in.

It is best to try and replicate the plant’s natural habitat as much as possible.

Doing so will make it easier to provide this foliage plant with its basic needs.

The proper setup and theme of the enclosure will make a big difference to the overall look and health of the plant.

Be sure to choose setups that are moist and high in humidity.

Here are recommended vivariums it will do well in:

    • Paludariums – Half aquatic/ half terrain-based enclosure.

    • Terrariums – Fully terrain-based enclosures with little to no aquatic features.

    • Ripariums – Mostly aquatic-based enclosures with some terrain features present.

    • Aquarium– Fully aquatic-based enclosure with little to no dry terrain.

Vivarium Placement

When making a suitable environment for Bacopa monnieri, there are several factors to keep in mind.

This plant should be planted on a substrate that is about 4 inches deep, as a more shallow depth can lead to poor growth.

The area surrounding the plant should also be sheltered from direct rays of light and direct water currents.


Bacopa monnieri does not require any special aquarium substrate for its growth, but a nutrient-rich soil mixture is recommended for optimum results.

This plant can also be grown in sand, gravel, or a combination of both.


Bacopa monnieri needs bright but indirect aquarium lighting to remain in optimal condition.

This means that direct sunlight is not necessary, and the light should be filtered by water or an aquarium hood.

Additionally, the plant should receive no less than 8 hours of light per day.
