Species of Dasya are found in both temperate and tropical water worldwide. All feature fleshy uprights, with irregular shaped branches and soft, hair-like filaments. A beautiful algae that has a deep, crimson red coloration. It is attached by a single holdfast, to hard bottom habitats as well as shells and coral fragments. Most species are found in shallow water to depths of 30 feet. Similar in composition to species of Halymenia, it is completely limp and slippery when out of water as it lacks any rigid structure. In the aquarium it grows fairly slow and needs moderate to high current and strong lighting to thrive. Most species prefer cooler water temperatures, so it can be a challenge to keep long term in some planted aquaria. Most species that are available in the aquarium trade are collected from the Gulf of Mexico and Atlantic from Florida. Dasya is not known to be palatable to fish or invertebrates.
