General Description
Hygrophila sp. 'Bold' is a visually striking aquatic plant species that first appeared in the aquaristic scene in the USA in 2006. Belonging to the Acanthaceae family, this plant exhibits remarkable variability in color and form based on its growing conditions, with the potential to develop intense reddish-brown to purple hues under optimal lighting and nutrient levels.
Aquarium Suitability
With a classification of being very easy to care for, Hygrophila sp. 'Bold' is a suitable choice for both beginner and experienced aquarists. It is adaptable to a range of water parameters and can thrive without the need for additional CO2 injection or intense lighting. However, for the most vibrant coloration and compact growth, providing ample light and micronutrient fertilization is recommended.
Demands and Hardiness
As indicated in the provided table, Hygrophila sp. 'Bold' thrives in a temperature range of 22-28°C and tolerates temperatures between 4-35°C. It requires medium to high lighting, a pH level of 5-8, and varying levels of nutrients such as carbon dioxide, iron, nitrate, phosphate, and potassium for optimal growth. The plant's carbonate hardness should fall within the range of 2-21.
Aquascaping & Usage
Hygrophila sp. 'Bold' serves well as a background or midground plant in aquarium layouts, adding depth and contrast to aquascapes. Its fast growth rate makes it suitable for filling in spaces quickly, and its distinctive appearance can create a focal point in planted tanks.
Propagation
Propagation of Hygrophila sp. 'Bold' is easily achieved through stem cuttings. The plant can be trimmed and replanted to establish new growth, making it a convenient choice for aquarists looking to expand their aquatic flora.
Habitat and Distribution
Originating possibly from Thailand, the exact species to which Hygrophila sp. 'Bold' belongs is still undetermined. It is known for its variable nature, both in aquatic and emersed forms, with emersed specimens showcasing a different appearance, including reddish-brown colors and glandular hairs. While not widely available commercially, this plant can be exchanged among aquarists in the USA with caution due to its resemblance to Hygrophila sp. 'Tiger'.
