Care
Water immersion and circulation
Zostera capricorni must remain fully submerged in freshwater or slightly brackish water. Maintain regular water circulation and supply of clear water to limit sediment buildup on the leaves. Partial water changes every 2 to 3 weeks promote its vitality. Avoid stagnant water that would encourage algae growth.
Light requirements
This seagrass needs moderate to strong light for good photosynthesis. Aim for 8 to 10 hours of lighting daily in an aquarium or pond. Insufficient light causes weakening and loss of basal leaves. However, avoid direct sunlight exposure in very confined spaces.
Substrate and planting
Plant Zostera capricorni in a mineral-rich substrate (volcanic gravel, fine sand, or specialized aquatic soil). Push the rhizome slightly into the substrate so it roots well, leaving the crown exposed. A nutrient-rich substrate promotes better growth and plant stability.
Nutrition and amendments
Apply complete liquid fertilizer (macronutrients and trace elements) every 2 weeks during the growing season. Aquatic plants absorb nutrients directly through their leaves and roots. An iron supplement can improve foliage coloration if it yellows.
Maintenance and pruning
Regularly remove yellow or damaged leaves by pinching them off at the base. You can divide the rhizomes every 6 to 12 months to rejuvenate clumps and create new plants. Avoid harsh cutting: prefer gentle and regular maintenance.
Prevention and common issues
Zostera capricorni can suffer from green or brown algae if light and water circulation are insufficient. Water that is too polluted or overloaded with organic matter promotes plant decline. Regularly check for the absence of deposits or necrosed leaves, and maintain stable water parameters.
Did you know?
Zostera capricorni is a seagrass naturally found in the coastal waters of the South Pacific, where it forms vital marine meadows for many fish and mollusk species. Its name "capricorni" refers to its distribution near the Tropic of Capricorn. In aquarium keeping, it is valued by enthusiasts for its elegant appearance and its role as a natural oxygenating plant.
Where to buy it
Best planted in spring or autumn, away from frost and heatwaves. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September, October.
