What is Moneywort (Bacopa monnieri) and Why is it So Popular?

Before we dive into floating it, let’s get properly introduced! Moneywort, known scientifically as Bacopa monnieri, is a true workhorse in the aquarium hobby. It’s beloved by beginners and seasoned aquascapers alike for its vibrant green color and hardy nature.

Key Characteristics of a Healthy Moneywort Plant

When you’re picking out Moneywort, look for stems that are sturdy and vibrant. Healthy plants will have full, lush leaves without any brown spots, holes, or transparency. You might see some small white roots sprouting from the stem nodes—this is a great sign of a vigorous plant ready to grow in your tank.

Planted vs. Floating: The Great Debate

Traditionally, Moneywort is sold as a background stem plant. Aquarists plant the stems into the substrate, where they grow upwards towards the light, creating a beautiful “wall of green.” This is a classic and wonderful way to use it.

However, its natural biology makes it an excellent candidate for floating. It doesn’t need to be rooted to thrive. This versatility is what makes it a superstar plant, allowing you to decide exactly how you want to feature it in your aquascape.

Common Problems with Floating Moneywort and How to Solve Them

Even with an easy plant like Moneywort, you might run into a few bumps. Don’t worry! Here are some common problems with will moneywort float on surface of aquarium setups and their simple solutions.

Problem: My Moneywort is “Melting”!

Cause: “Melting” (when leaves become transparent and disintegrate) is most often due to acclimation shock. The plant is adjusting from the conditions it was grown in (often emersed, or out of water) to the conditions in your tank. It can also be a sign of a severe nutrient deficiency.

Solution: Be patient. Remove any heavily melted leaves so they don’t decay in your tank. As long as the stems are firm, the plant will almost always bounce back and start putting out new, submerged-adapted growth. Ensure you are dosing a good liquid fertilizer.

Problem: The Leaves are Turning Yellow and the Stems are Leggy.

Cause: This is a classic sign of a nutrient deficiency, usually a lack of nitrogen or iron. “Leggy” growth (long spaces between leaf sets) indicates it’s stretching for resources.

Solution: The fix is simple: fertilize! Start dosing a comprehensive liquid fertilizer regularly. You should see new growth coming in much greener and more compact within a week or two.

Problem: It’s Taking Over My Entire Tank Surface!

Cause: This isn’t really a problem—it’s a sign of success! It means your plant is healthy and happy.

Solution: Regular maintenance is your best friend. Trim the plants back once a week, removing about 20-30% of the mass. Use the containment ring trick we mentioned earlier to keep it in one section of the tank. The excess trimmings make a great gift for fellow hobbyists!

Frequently Asked Questions About Floating Moneywort

Does floating Moneywort need fertilizer?

Yes, this is non-negotiable. Because it cannot draw nutrients from the substrate, a comprehensive liquid fertilizer dosed directly into the water column is essential for its health and vibrant green color.

Can I switch my Moneywort from being planted to floating?

Absolutely! You can gently pull the stems out of your substrate, rinse any substrate off the roots, and simply place them on the water’s surface. They will adapt very quickly.

Is floating Moneywort good for betta fish?

It is one of the best plants you can choose for a betta tank. Bettas love the cover it provides, feel more secure under it, and will often use the leaves to anchor their bubble nests. It perfectly mimics their natural habitat.

Will my filter outflow bother the floating Moneywort?

It can. A strong current from a hang-on-back filter can push the plants around or even submerge them. You can buffer the flow with a sponge or position the plants on the opposite side of the tank. Using a containment ring also helps keep them out of the direct path of the current.
