Founded in 2003 by Russ Kronenwetter, Gulf Coast Ecosystems began by offering marine macroalgae online to hobbyists. Over the years, we’ve grown into a trusted source for live marine plants, invertebrates, and gorgonians, supplying hobbyists, pet stores, public aquariums, universities, and research facilities. Now operated by Dexter Hill, Aimee Call, and Thomas Howard, our team continues the mission of providing healthy, sustainable saltwater life while sharing the beauty of the ocean.
