Mark Collier

Founder & CEO

You may know of Mark Collier by his other “name”— the Arizona Fish Guy. Mark has been designing, installing and maintaining custom aquariums for residential and commercial clients for nearly 25 years. He estimates his creations number several hundred.

The Phoenix native says he was fascinated by fish and aquariums as a boy. His father was a hobbyist, and Mark spent much of his free time at the local fish store. He jokes that he was there so often the owner felt compelled to offer him a job, and he started working for the company after graduating from high school.

For the next 10 years, he learned all he could about designing and installing tanks while also doing extensive research on fish. In the late 1990s, he branched out and started his own firm, Custom Marine Aquaria.

Mark says that one of the things he enjoys most about his job is coming up with designs that push the boundaries of typical tanks.

Mark approaches each and every installation as if it were a custom masterpiece whether building a 75 gallon free standing aquarium with standard cabinetry or a 2500 gallon built in with exquisite detail and top of the line life support.

“Everyone always asks me, what’s the largest tank you’ve ever built? My largest to date is a 30 foot nearly 4000 gallon aquarium in a beautiful home in Fountain Hills, which landed me in the New York Times. The two largest aquariums that we maintain are 11,000 gallons and 18,500 gallons, one saltwater one freshwater.”

Mark is one of the best in the industry. He works hard on the details of the environments he builds. My tank turned out fantastic and I couldn't be happier! Thank you AEM for your awesome designs!

Mark is an exceptional tank designer and manufacturer. He designed Bass Pro Shops main tank in the lobby. All the customers are raving about how awesome it looks! Thanks AEM and Mark for all your hard work on the logistics of the entire project!

We were looking for an alternate solution for our huge salt water tank at home and needed an expert in steel stands and custom acrylic work. Mark is your guy for this, for certain! We couldn't be more pleased with the work he did for us. Thanks Mark!

Wow, just wow! This company is awesome at tank design!! I looked all over the Valley for a tank builder that could fulfill my needs for a tank for my business. They manufactured the tank, welded the steel frame, and wrapped the frame in beautiful wood to compliment the décor.

Mark and his crew designed my tank and helped install it. I can't believe how real the faux reef insert looks. It is absolutely stunning! His skills with reef design are so good that I was able to recommend him to a bunch of my friends. Thanks again Mark!
