Roy Lee

Roy's obsession with reef tanks started when he was gifted a small coral from a close friend. Then, like most, his collection grew as he purchased bigger and bigger tanks.

By early 2013, Roy had set up so many tanks that there wasn't enough room in his apartment to house all the fish and coral he had collected. It was then that he decided to frag and start selling acclimated corals and fish to fellow hobbyists.

After encountering so many beginner and experienced hobbyists' passion to maintaining a healthy tank, Roy decided to start Reef Tank Advisor to help address thes common questions that people had.
