Our History

Tenji Aquarium Design + Build was started in 2001 by three former Monterey Bay Aquarium employees. Since then, we’ve worked on projects based in eight different countries and 30 different states, and can’t wait to keep adding to that list. From jaguars to flamingos to lobsters and everything in between, we have built more tanks and life support systems than we can count. Enjoy learning about some of the milestones of our journey in the timeline below.

Before 1990: The Life Aquatic

An interest in all things aquatic was developed at an early age for the Tenji principals. Ed was particularly drawn to snorkeling, while Mark felt happiest while on a boat.

2001: Our First Project

Our first project! Tenji is started after being asked to consult on a sustainable shrimp farm. The waste water from the shrimps, which was high in ammonia, was being used to grow tomatoes.

2002: Our First Tank

The first tank we ever built was a freshwater Amazonian for a client in our backyard: Big Sur, California.

2002: Giant Residential Tank

2002 also saw the very first private residence installation we completed. The tank was a massive one, a truly public aquarium-sized project in someone’s home.

2003: International Adventures

We head across the pond on our first international project. Tenji was asked to consult on the BIOTA Aquarium in London, and we got some sightseeing in during the trip.

2005: LL Bean Flagship Store

Our first commercial project was at LL Bean’s flagship store in Freeport, Maine. We built a 3,500 gallon tank that has an artificial current that reflects the local riverbed ecosystem.

2005: First Time Authors

In 2005, we added another title to our ranks: that of authors! We contributed to the Under the Sea poster book, all about public aquariums.
