John Tullock 150px.jpg John H. Tullock is a zoologist and one of America's leading proponents of environmentally sound aquarium keeping.

A native of Tennessee, John received a Master of Science degree from the University of Tennessee in 1976, studying ichthyology under Dr. David Etnier, who is perhaps best known for his discovery of the snail darter.

After teaching college-level biology for a number of years, John and a group of partners founded Aquatic Specialists in 1987, which grew to become one of the largest direct-to-consumer national suppliers of marine fishes, invertebrates, and live rock to aquarists. In 1994, he moved on to pursue a career as a writer and consultant to the aquarium trade. He is the author of over a dozen books, including the popular Natural Reef Aquariums. His numerous articles have appeared in every major aquarium publication.

An orchid enthusiast, John has also written about his favorite plants. His Growing Hardy Orchids (2006, Timber Press) was named by the American Horticultural Society as one the year’s five best garden books.

He is the founder of the American Marinelife Dealers Association, an organization of aquarium-industry businesses that promotes environmentally sustainable practices and education for conservation awareness. He was a member of the steering committee that helped create the Marine Aquarium Council in 1997. John also serves on the board of Conservation Fisheries, a non-profit that operates the only private hatchery in North America that raises endangered and threatened species of native American fish for habitat restoration and species-recovery projects.


John is an avid outdoorsman, with a particular fondness for exploring the Cumberland and Appalachian Mountains near his home in Knoxville, Tennessee.
