Oceans Aquarium Design in Signal Hill, California, is a saltwater aquarium design and installation company led by owner Golan, whose name appears in nearly every customer review — a testament to his hands-on involvement in every project. This isn't a typical fish store with aisles of tanks and bags of gravel. It's a full-service custom aquarium operation that designs, builds, installs, and maintains showpiece saltwater tanks for homes, lobbies, and commercial spaces across Southern California.
The scale of work here is impressive. Projects range from first-time hobbyist setups to a 1,650-gallon built-in aquarium for a Newport Coast home requiring structural remodeling and coordination with a general contractor and design team. A 600-gallon residential installation left the homeowner calling it the best purchase they ever made for their house.
Interior designers and commercial clients return because Golan's team coordinates seamlessly with other contractors, adapting to complex builds without friction. What sets Oceans Aquarium Design apart is the end-to-end experience. Golan visits homes, listens to ideas, and develops creative solutions within the client's budget.
The process extends well beyond installation — the company handles quarantine protocols for new fish, provides expert fish selection recommendations, and runs ongoing biweekly maintenance visits handled by technicians like Dave. One long-term client has relied on them for all saltwater tank needs since 2017. The consultation process is genuinely collaborative.
Multiple reviewers note that Golan incorporates client suggestions without ego, blending his deep saltwater expertise with what the customer envisions. A client with 20 years of fishkeeping experience and tanks up to 400 gallons described the finished custom tank and stand as absolutely perfect. From a donated aquarium bringing joy to residents at Heritage Pointe to lobby installations designed for maximum wow factor, Oceans Aquarium Design transforms spaces.
Their lifetime support approach and Golan's responsive communication — by email, text, or in person — make the ongoing relationship as strong as the initial build.

If you ever dreamed of having your own salt water tank as a hobby, or if you are experienced in collecting fish, Golan at Oceans Aquarium Design is the professional for you. As a first time tank owner, Golan has been patient and caring, sharing his expertise with me through every stage of my new hobby. From the tank design to the quarantine process, fish delivery and beyond, Golan has been an incredible advisor to me. His response to my emails is always prompt and to my texts are excellent. Dave, his maintenance service professional, who visits my home biweekly, is timely and diligent in his skill. I so enjoy planning for new additions to my tank and trust that I have the best team around to help me care for my saltwater friends!

We had such a positive experience working with Oceans Aquarium Design on our saltwater fish tank. From the start, they were very willing to work with us — visiting our home, listening to our ideas, and coming up with creative solutions that fit both our space and our budget. They were accommodating throughout the entire process, and it really showed in the final result. Our tank is not only beautiful but also fits perfectly into our home. We couldn’t be happier with the outcome and highly recommend them!

We had them do a 600+ gallon tank for us and they did an absolutely beautiful job from planning to delivery and then on to maintenance. It's a piece that literally everyone stops to talk about it when they see it. I grew up with smaller tanks in my teens so decided to go big now that I've finally reached the 'grown up' stage. The tank was the best purchase for our house we've ever done. Our La Cantina door supplier was here and said of all the homes he's been in this one was the best. My wife loves it too, so guys - there's hope. Golan and his team do an absolutely incredible job.

I recently had a custom fish tank built by Ocean’s Aquarium Design and I couldn't be happier with the results! From the initial consultation to the final installation, the entire process was seamless and professional. Golan and his team took the time to understand my vision and made expert recommendations that truly elevated the design. The craftsmanship is top-notch, and the attention to detail is evident in every aspect of the tank. My fish are thriving, and the tank has become a stunning focal point in my home. The customer service was excellent as well—they were responsive, knowledgeable, and genuinely cared about my satisfaction. If you're looking for a unique, high-quality custom fish tank, I highly recommend Ocean’s Aquarium Design. They exceeded my expectations in every way!

Golan's attention to detail is great. We also went a bit over time budget, and the team was very flexible with lifetime support.
