Our Mission
At Corals Unlimited, we believe that anyone who wants an aquarium, whether freshwater, saltwater, or reef, should be able to enjoy one. Our goal is to make aquarium keeping accessible, sustainable, and rewarding for hobbyists of all experience levels throughout Maine and beyond.
How It All Started
When I began reef keeping over 19 years ago, everyone around me said it was too hard or a waste of time and money. While I did make mistakes and spend more than I expected, those lessons became the foundation for everything I do today.
Back then, few people shared their successes or failures publicly. I wanted to change that, so I started the Mad Hatter’s Reef YouTube channel to help others learn from my journey. When the hobby began to decline in Maine, I decided to take things further and create a place that would reignite passion for aquariums in our state. That vision became Corals Unlimited.
Our Store in Topsham, Maine
Located in the Topsham Fair Mall, Corals Unlimited is Maine’s home for saltwater and freshwater aquariums, live fish, and aquacultured corals. What began as a successful online store grew into a full-service brick and mortar location where hobbyists can see, learn, and experience the beauty of marine life in person.
Our goal has always been to provide Maine hobbyists with the aquarium store they deserve, one that leads the way in sustainable aquaculture and education.
Sustainability at the Core
Over 70% of our corals are aquacultured, propagated right here for multiple generations, ensuring their health, longevity, and minimal environmental impact.
By focusing on aquacultured livestock, we help protect wild reefs and reduce the need for ocean collection. As climate change and pollution continue to affect natural reefs, sustainable aquaculture is the future of this hobby, and we’re proud to be part of that movement.
Education and Community
We believe education is the key to long-term success in aquarium keeping. Corals Unlimited offers resources both in store and online to help aquarists of every skill level learn about water chemistry, equipment, and livestock care.
Through our YouTube channel, social media, and in-store workshops, we’re committed to sharing knowledge and inspiring the next generation of reef keepers.
