About
I truly love what I do. I have been a hobbyist for almost my entire life and starting Diamond Aquatics was a dream come true for me but I would say the most important reason to hire me is that I will treat your aquarium and fish as if they are my own. I pay attention to detail and handle every situation with consideration for the lives of the animals in your tank first. Lastly, I will never try to sell you products that you don’t need or fish that will not do well in your system just to make a few bucks.

Frank kept me informed about his appointment and arrived early. This can be half the problem! He was very pleasant, informative, answered my questions cleaned up my tank beautifully. He was quite professional, and I would definitely use him in the future.
Nick did an excellent job in cleaning our 125 gal fish tank, it was neglected for a bit due to my husband having back surgery, the tank looks great he definitely knew what to do to get the job done. Thanks Nick

FAQs
What education and/or training do you have that relates to your work?
Diamond Aquatics is dedicated to delivering the highest standard in customer service and quality products. Our services include custom and standard aquarium design, moving and delivery, installation, and routine maintenance packages tailored to fit your needs.
I founded Diamond Aquatics was in 2008. I have been an aquarium hobbyist since 1988 and working in the aquarium industry since 1996. Since then, part of my career was spent at Absolutely Fish where I revived their dying maintenance branch and built it into a thriving part of their business. I then went on to establish Diamond Aquatics in 2008 in order to provide the best customer service and product selection in the market.
I truly love what I do and I look forward to working with you to build your aquarium and tailor fit it to you and your home.
What types of customers have you worked with?
Diamond Aquatics works with everyone! Our clients include professional athletes, actors, plumbers, customer service specialists, investment bankers, hedge fund managers, doctors, dentists and many others. Let us know how we can help you!
