Common name: Gelidium Seaweed

General information

Gelidium microdon is a species of red algae that belongs to the family Gelidiaceae. It is commonly known as Gelidium Seaweed and is recognized for its role in the production of agar, a gelatinous substance widely used in the food industry and in scientific applications. In the reef aquarium, Gelidium species can add a natural and diverse element to the aquascape, providing a habitat for small invertebrates and a grazing area for herbivorous fish.

Care

Gelidium microdon requires moderate to high lighting to thrive in a reef aquarium. It prefers strong water movement to mimic its natural environment, where it is often found in intertidal zones with significant wave action. This red algae can be attached to live rock or other substrates, and it benefits from the addition of trace elements and nutrients to promote healthy growth.

Symbiosis

While Gelidium microdon does not have any specific symbiotic relationships that are notable in the context of reef aquariums, it does contribute to the overall ecosystem by providing shelter and food for small invertebrates and serving as a natural filtration system by absorbing excess nutrients from the water.

Habitat

Gelidium microdon is typically found in cooler marine waters and is widely distributed along rocky coastlines. It grows in the intertidal to subtidal zones, often forming dense mats that can withstand strong currents and wave action.
