Julian Jacquot

Best aquarium shop I've been to in years! The tanks are so clean and well laid-out. ARC has a huge variety of fish, coral and plants, and all of the fish are healthy and vibrant, and aren't overcrowded. Eric was very kind and helpful, and his passion about aquatics was apparant. Will definitely recommend ARC to my friends and family.
