Decorative, robust and easy to plant , the Hygrophila corymbosa 'Siamensis 53B' in a mini pot is perfect for creating a dense and natural plant background . With its finely textured leaves with sometimes coppery reflections under good lighting , it transforms the bottom of the tank into a real small aquatic garden. Thanks to its moderate growth and its very simple needs, it adapts easily to low-tech aquariums, even without CO2 injection. Sold in a mini coconut pot, it is ready to plant effortlessly. It is a perfect choice for those who want a plant that is both aesthetic, practical, and requires little maintenance.

Hygrophila corymbosa 'Siamensis 53B' stands out for its ability to quickly form a beautiful, compact bush, perfect for the background of the tank. This variety from Thailand is appreciated for its natural bushy shape and numerous lateral shoots. In an aquarium, it can reach up to 40 cm in height and approximately 12 cm in width, which allows it to elegantly hide technical equipment or structure the plant decor.
Its light green leaves are slightly smaller than those of the classic 'Siamensis' version. Under the right lighting, they take on a stunning coppery sheen, adding a highly desirable visual effect. This warm hue makes it even more attractive in natural or Asian-style aquariums.
The mini pot format is a real plus: the plant arrives with its roots already well developed in a coconut fiber support. No need to remove anything, just plant it directly in the ground . In addition to being quick, this method is gentle on the plant, which adapts more easily to its new environment. It anchors quickly and begins to grow without difficulty.
It appreciates a nutritious substrate to express its full potential, but it also grows very well in simpler soils, as long as a minimum of nutrients are available. Its tolerance to different water parameters makes it a safe bet for all types of aquariums.
If you're looking for an easy-to-grow plant, you'll love the 53B. It thrives in water temperatures between 18 and 30°C , with a pH between 5.5 and 8, and a wide range of hardness. Even in moderate light, it thrives and looks great. No need for sophisticated equipment or complicated maintenance.
Its average growth allows it to be pruned as needed, which stimulates the appearance of new side shoots . To propagate it, nothing could be simpler: cut off the ends and replant them. It takes cuttings very well and therefore allows you to quickly expand your bed.

In addition to being easy to maintain, this Hygrophila is also perfectly suited to creating a natural atmosphere . It combines wonderfully well with aquarium roots or aquarium sand for a natural and harmonious look. Its dense shape also makes it easy to hide technical elements such as the filter .
Even in a low-tech tank, it perfectly fulfills its decorative role. Thanks to its easy maintenance and its very plant-like appearance, it fits equally well in nano-aquariums as in larger tanks. A true little plant gem to adopt without hesitation.
