General Description
Syngonanthus macrocaulon, a plant of the Eriocaulaceae family, is a striking aquatic plant originating from soft blackwater rivers and rivulets near the mouth of the Amazon river in Brazil. Initially introduced to the aquarium hobby as Tonina sp. 'Belém', it was later correctly identified as a member of the genus Syngonanthus by botanists. Known for its unique habit and growth form, this plant stands out in aquariums due to its long-stalked head-shaped flowers that appear in groups on the shoot tip, reminiscent of species in the Eriocaulon genus.
Aquarium Suitability
Syngonanthus macrocaulon, though highly demanding, is considered suitable for aquariums, particularly as an accent plant in the midground. Its vertical growth rate is moderate, with a preference for developing lateral shoots. To thrive in an aquarium, this plant requires intense lighting (around 1 watt per liter), carbon dioxide supplementation, soft water with low general and carbonate hardness, and adequate iron levels to maintain its vivid green color.
Demands and Hardiness
As indicated in the detailed requirements above (see table), Syngonanthus macrocaulon poses significant challenges to aquarists due to its need for specific water parameters, lighting conditions, and substrate preferences. It is crucial to provide the plant with suitable care, including regular trimming of the uppermost stem portions and ensuring the presence of mycorrhiza fungi in the substrate vicinity to enhance its beauty.
Aquascaping & Usage
In aquascaping, Syngonanthus macrocaulon shines as an eye-catching element, particularly when placed in the middleground of planted aquariums. Its aesthetic appeal is further enhanced when combined with grasslike plants such as Sagittaria subulata or incorporated into layouts featuring members of the Eriocaulaceae family, creating visually stunning aquascapes.
Propagation
The propagation of Syngonanthus macrocaulon primarily involves taking cuttings from the upper 4 cm of the plant stem and replanting them in the substrate. This method promotes root growth in the cuttings and maintains the plant's overall appearance. Longer cuttings are discouraged as they may lead to an unsightly look during development.
Habitat and Distribution
Found in soft blackwater rivers and rivulets near the Amazon river's mouth in Brazil, Syngonanthus macrocaulon thrives in its natural habitat alongside other aquatic flora. Its distribution is limited to these specific regions, where it exhibits its unique growth habits and benefits from the symbiotic relationship with mycorrhizal fungi, enhancing its overall health and beauty.
