Creating a Lush Aquarium with Dwarf Baby Tears

Dwarf Baby Tears: A Guide to Care and Maintenance

Dwarf Baby Tears, also known as Hemianthus callitrichoides, are aquatic plants that have gained popularity among aquarium enthusiasts for their lush green foliage and striking aesthetic. These plants are commonly used as foreground plants in planted tanks and aquascapes, but they can be challenging to establish and maintain.

In this article, we will explore how to care for Dwarf Baby Tears, their habitat, and why they are so desirable among aquarium lovers.

Dwarf Baby Tears as Foreground Plants

Dwarf Baby Tears are popular for their small size and the lush, green carpet they provide for your aquarium’s foreground. These plants have small leaves that are around 1-2mm in size, making them ideal for creating a dense, carpet-like look in your tank.

One important thing to note is that Dwarf Baby Tears do not do well in environments with high water flow. They need a stable base in which to grow, which is why they are often planted in substrate.

Difficulty in Establishing and Care

One common issue when it comes to Dwarf Baby Tears is the difficulty in establishing and maintaining the plant. They require specific conditions to thrive in an aquarium, which many aquarium enthusiasts may find challenging to achieve.

One of the most important factors in establishing Dwarf Baby Tears is lighting. They need to be exposed to at least 3-4 watts of light per gallon of water to grow well.

This means that if you have a 20-gallon tank, then you should have a light source that provides between 60-80 watts of light. Another essential factor for Dwarf Baby Tears to thrive is carbon dioxide (CO2).

Carbon dioxide is a necessary nutrient for all plants, and in low-light conditions, it can be even more crucial. If your aquarium is not adequately oxygenated, then your plants may have difficulty photosynthesizing, and you may notice yellowing or browning of the leaves.

Apart from these lighting and carbon dioxide requirements, you should also consider water hardness and temperature. Dwarf Baby Tears need soft water with a pH of between 5 and 7.

They also need to be kept at a temperature of around 22-28C.

Name and Natural Habitat

Dwarf Baby Tears have a scientific name of Hemianthus callitrichoides and are native to Cuba. They are commonly found in the shallow waters of rivers and streams with rich nutrient content.

Growing amongst rocks and sand, they have adapted to grow in low light conditions and have become popular with aquarium enthusiasts for their small size and attractive foliage.

Natural Habitat in Shallow Waters with High Nutrient Contents

Dwarf Baby Tears are native to shallow waters with high nutrient content. When planting in an aquarium, you should consider this natural habitat and replicate it as closely as possible.

Adding a nutrient-rich substrate can help provide the nutrients that Dwarf Baby Tears need to thrive. Additionally, you can add fertilizers that are rich in iron, potassium, and nitrogen to enrich the water.

Another important factor to consider is the presence of algae. Algae can be a significant issue when growing Dwarf Baby Tears.

To reduce the growth of algae in your tank, avoid overfeeding your fish and ensure that the tank is kept clean.


In conclusion, Dwarf Baby Tears are beautiful aquatic plants that can be a valuable addition to any planted tank or aquascape. They are, however, somewhat challenging to establish and maintain, requiring specific lighting, temperature, and nutrient conditions to grow well.

By understanding the scientific name, natural habitat, and requirements of Dwarf Baby Tears, you can create an environment conducive to their growth and long-term health.

Tank Requirements for Dwarf Baby Tears

Dwarf Baby Tears, also known as Hemianthus callitrichoides, require specific tank requirements to grow and flourish. In this section, we will explore the lighting, substrate, and water parameters required for keeping Dwarf Baby Tears in an aquarium.

High Demand for Light and Nutrients

Dwarf Baby Tears require high levels of light to grow properly. At least 3-4 watts of light per gallon of water is recommended for them to thrive.

Lighting fixtures with a color temperature of 5000k-10000k are best suited for growing these plants. The high demand for light also requires that you provide enough nutrients.

You can use liquid or solid fertilizers, or you can use a soil-based substrate that naturally releases nutrients over time. Using fertilizers with high levels of iron, potassium, and nitrogen will help your plants grow healthy and strong.

In addition to providing nutrients directly to the plants, you can also implement a CO2 injection system to help your plants absorb more carbon dioxide. This, in turn, will help them grow faster and more vibrant.

Stable Tropical Water Temperature and pH

Temperature and pH are critical factors when it comes to keeping Dwarf Baby Tears in your aquarium. They prefer a tropical temperature range of 22-28C.

Since these plants come from Cuba, where the water is a bit on the warm side, they do well with slightly higher water temperatures. As for pH, these plants prefer the softer side of the scale.

A pH range between 5 and 7 is optimal for Dwarf Baby Tears. If your aquarium water is too hard, you can add a water softener or use reverse osmosis (RO) water to maintain the proper pH level.

Substrate Should be Fine-Grained and Rich with Nutrients

Dwarf Baby Tears require a good substrate to root in. A fine-grained, nutrient-rich substrate is ideal for growing these plants.

The finer the substrate, the easier it is for your plants’ roots to grow and take hold. You can use sand, or you can opt for a soil-based substrate such as aqua soil.

Soil-based substrates are highly recommended as they provide the plants with a ready source of nutrients that can last for several months. This means that you don’t have to add fertilizers very often.

When using soil-based substrates, it’s essential to monitor the aquarium’s water chemistry. The substrate will break down over time, releasing nutrients and altering the water parameters.

Tank Mates

Dwarf Baby Tears make an excellent addition to an aquarium, especially when paired with other plants and peaceful freshwater fish. Here are some recommendations when it comes to tank mates for Dwarf Baby Tears.

Looks Best Among Other Foreground Plants of Different Colors

Dwarf Baby Tears are often used as foreground plants. They look best when paired with other foreground plants of different colors and textures.

Some excellent options include Monte Carlo, Pogostemon helferi, and Staurogyne repens.

Should be Kept With Calm and Peaceful Freshwater Fish

When selecting tank mates for Dwarf Baby Tears, it’s essential to choose fish that are calm and peaceful. Avoid aggressive fish that may nip at the plants or uproot them.

Good options include small tetras such as neon tetras, rasboras, or guppies. Snails can also be added to help keep the tank clean.

It’s best to avoid large, bottom-dwelling fish as they may disturb your plants’ roots. Commonly Used for Breeding/Spawning Tanks

Dwarf Baby Tears are a popular choice for breeding and spawning tanks.

The thick carpet of greenery they provide can help to create a natural habitat for the fish to breed and lay their eggs. When using Dwarf Baby Tears in breeding or spawning tanks, it’s essential to keep the water clean and maintain optimal water parameters.
