Hemianthus callitrichoides, also known as "dwarf baby tears" or "HC," is a small, herbaceous aquatic plant native to Cuba. It is commonly used in the aquarium hobby as a foreground plant due to its delicate, lush appearance and small size.
HC grows in a creeping manner, with small, round leaves that grow densely along thin stems. The leaves are typically a bright green color, but may take on a reddish or yellowish hue depending on the lighting and nutrient levels in the tank. HC is a slow-growing plant, reaching a maximum height of only a few inches.
One of the main challenges of keeping HC is maintaining proper lighting. HC requires high levels of light in order to thrive, with a recommended range of 2-3 watts per gallon. Additionally, HC requires a substrate rich in nutrients, as it absorbs most of its nutrients through its roots. Without a suitable substrate, HC may struggle to grow or even die off.
Another important aspect of keeping HC is pruning. As the plant grows, it is important to regularly trim off any dead or dying leaves, as well as any excess growth. This will help to keep the plant looking its best and prevent it from becoming overcrowded.
HC is a popular choice for aquascaping due to its small size and versatility. It can be used as a standalone plant or incorporated into a larger design, and is often used to create a carpet-like effect in the foreground of the tank. It is also relatively easy to care for, making it a good choice for beginner aquarists.
Despite its delicate appearance, HC is quite hardy and can tolerate a wide range of water conditions. It is tolerant of a pH range of 6.5-7.5 and can survive in temperatures as low as 60 degrees Fahrenheit. However, it is important to maintain a consistent temperature and avoid sudden fluctuations, as HC is sensitive to such changes.
In conclusion, Hemianthus callitrichoides is a small, attractive plant that is popular in the aquarium hobby due to its delicate appearance and versatility in aquascaping. It requires high levels of light and a nutrient-rich substrate in order to thrive, and regular pruning is necessary to keep it looking its best. Despite its delicate appearance, HC is a hardy plant that can tolerate a wide range of water conditions, making it a good choice for both beginner and experienced aquarists.
