Common name: Fine sea grass

General information

Halodule uninervis, commonly known as Paddle Grass or Narrow Leaf Seagrass, is a marine angiosperm belonging to the family Cymodoceaceae. It is a small, fast-growing seagrass species that plays a crucial role in coastal ecosystems. This seagrass is characterized by its narrow, ribbon-like leaves and can form dense meadows, providing important habitat for a variety of marine organisms.

Care

In the aquarium, Halodule uninervis requires a sandy substrate to anchor its roots and adequate lighting to support photosynthesis. It is a hardy species that can adapt to a range of water conditions but thrives best in stable environments with clean, nutrient-rich water. Regular pruning may be necessary to maintain its growth and prevent it from overshadowing other plants or corals.

Symbiosis

Halodule uninervis forms the foundation of a complex web of life. It offers shelter and food to a myriad of organisms, including juvenile fish, invertebrates, and endangered species like seahorses. Its presence can enhance the biodiversity of a reef aquarium by attracting and supporting these beneficial species.

Habitat

This seagrass is found in shallow, sandy or muddy bottoms in tropical and subtropical seas around the world. It is commonly seen in lagoons, estuaries, and along the coastlines, where it helps to stabilize sediment and improve water quality.
