Instead, this Bellevue-based company has built a remarkable reputation over more than two decades by bringing aquariums to the places people gather: medical clinics, dental offices, retirement communities, schools, corporate lobbies, and private homes. Their business is full-service aquarium installation and maintenance, and based on the consistency of their reviews, they've mastered it. The company deploys a team of dedicated technicians — Alan, Brent, Bill, Phil, Graham, and Tom among them — each assigned to specific clients, many for years or even decades. One reviewer notes Bill has maintained their tank for over 15 years; another mentions a 26-year relationship with the company. That kind of longevity speaks volumes. These technicians handle everything from routine cleanings and water quality management to fish health assessments, habitat rearrangement, and stocking recommendations. Clayton's reach extends well beyond freshwater community tanks. Brent specializes in saltwater setups, carefully advising clients on species compatibility. Phil tends to a beloved office puffer fish that serves as a workplace mascot. Bill maintains two koi ponds for a client, managing filtration, seasonal care, and water clarity with the kind of precision that keeps fish visibly healthier and more active. Tom services aquariums at schools and dental offices across the area, creating calming environments that residents, patients, and children gravitate toward. What stands out across nearly every review is how these technicians interact with the people around the tanks — patiently fielding questions from curious retirement home residents, educating schoolchildren about fish species, and keeping office staff updated on their aquarium's inhabitants. At Clayton Aquarium, the tank isn't just equipment to maintain; it's a living centerpiece that connects people. For any Bellevue-area business, institution, or homeowner wanting a professionally maintained aquarium without the hassle, Clayton has been the trusted name for decades. ## Specializations - **Water Types**: Freshwater, Saltwater, Pond - **Livestock & Products**: Koi, Puffers - **Services**: Tank Maintenance, Tank Setup, Tank Cleaning, Pond Services, Consultation - **Known For**: Premium Equipment, Knowledgeable Staff, Beginner Friendly, Healthy Fish ## Highlights - Full-service aquarium and koi pond maintenance across the Bellevue area for over 26 years - Dedicated technicians assigned to each client, with some relationships spanning 15+ years - Services freshwater, saltwater, and pond environments in offices, schools, clinics, and retirement communities - Technicians provide fish health education and species recommendations tailored to each setup - Maintains specialty setups including koi ponds and saltwater puffer fish tanks ## Customer Reviews **"Isabella Bronstein"** - 5/5 - a week ago > Great to work with!

His knowledge, attention to detail, and genuine care for the health of the fish and the ponds really stand out. He is extremely reliable, thorough, and always takes the time to explain what he’s doing and why — from water quality and filtration to fish health and seasonal maintenance. Since Bill started maintaining my ponds, the water has stayed crystal clear and my koi have been healthier and more active than ever. It’s rare to find someone who is not only highly skilled but also truly passionate about their work, and Bill is exactly that. If you’re looking for someone you can completely trust with your koi pond, I highly recommend Bill at Clayton Aquarium. You’ll be in excellent hands. **"Ashley Hendrickson"** - 5/5 - a week ago > Phil is our go to fish guy! He is very prompt whenever we have had to call him regarding one of the fish. He takes very good care of the tanks in our building. **"Muriel Haegele"** - 5/5 - a week ago > While visiting a friend in the retirement home we observed "Tom the fishman" servicing the aquarium and patiently discussing the different fish with curious residents. It was a joy to watch their interaction. I noted that it was a Clayton Aquarium tank which i was familiar with because they also service the tank at my dentist office. **"Kat J"** - 5/5 - a week ago > Brent consistently shows great care and attention to detail when it comes to our saltwater tank.
