About
Caesar's Tropical Fish Factory has been a Santa Rosa, CA institution for decades, a locally owned aquarium store that longtime customers describe as feeling more like a free mini-aquarium than a retail shop. Spread across three rooms of tanks, including a dark, blue-lit water room that regulars compare to walking through a zoo aquarium, plus a backyard full of outdoor koi ponds, it's the kind of place where kids press their faces to the glass and adults leave with a new obsession. The freshwater selection runs deep, from bettas and community staples to the pygmy corydoras and exotic species that keep hobbyists coming back.
Saltwater aquarists are just as well served; several reviewers call Caesar's their five-year go-to for everything their marine tanks need. Out back, koi for sale in Santa Rosa, CA share space with comets, water lilies, and native marginal pond plants in season, and pond keeper Markus comes up by name as someone who genuinely knows his stuff. " The dry-goods side covers filters, charcoal, medications, tanks, and stands, everything available in Santa Rosa, CA to start a system or rescue a struggling one.
One customer came in for fin rot treatment for a betta and walked out with both the right meds and a thorough education in betta care. Beyond the sales floor, the team offers aquarium cleaning and maintenance, custom and acrylic tank builds, and hands-on setup: one reviewer bought a 75-gallon tank after Markus walked her through quotes, then had his crew set it up at her home and transfer her fish in under an hour. What ties it all together is the staff.
Names like Phoenix, Javier, and Markus surface again and again, patient, knowledgeable, and happy to help a nervous first-timer or a 40-year veteran alike. 7 stars, this Sonoma County fish store stays well worth the drive from across the North Bay.

Customer reviews
“If you have a pond go talk to Markus. He is extremely knowledgeable and friendly staff.”
— Dennis Jennings4.0a week ago“Very good selection of freshwater tropical fish. Lots of koi in fun outdoor ponds and native marginal plants in season. Quarantine any outdoor fish! Always lots of people on hand to answer questions. No live foods for freshwater (ie daphnia). Fun just to stop and look at the tanks and koi ponds.”
— Gavin W4.02 weeks ago“Had fun looking at the exotic fish!🤩”
— K Z5.03 weeks ago“Great fish store, nice variety”
— Talushia Duquette5.0a month ago“The tanks in the store are always very clean and beautifully displayed. I mentioned that I wanted a new tank that was as attractive as theirs. Marcus showed me various options and provided some quotes. I purchased a 75 gal tank. He then arranged for their staff to come to my house to set up the new tank and transfer my fish from the old tank. The team was very friendly and completed the job within an hour. Marcus and the staff are always friendly and knowledable. I love my new tank and Thank Marcus for all his help. I definitely recommend Ceasar's Tropical Fish Store.”
— Nancy Dami5.0Edited 2 months ago“Every time I come in to Caesar‘s I have a stellar experience. I’m constantly looking for advice to help my tank thrive the best it can and I am extremely happy with the advice and suggestions I received during my visit yesterday. Everyone is very knowledgeable and extremely helpful when it comes to making the right choices for your aquarium. I look forward to continuing my visits to this store!”
— leesoup5.03 months ago“This place is awesome! So many cool fish to look at. They had exactly what we needed and all the employees were so nice and helpful even 10 minutes before they closed!”
— Patricia Hendricks5.03 months ago“I went back for the first time in 4 or 5 years. It's exactly the same in the best sense. The place is clean, the fish and aquatic creatures are happy. The staff is quick to help and friendly. The dark-blue-lit-water-room part of the store is so cool to walk around in. It honestly feels like a zoo aquarium. It would be cool to have informational plaques to learn about behavior and caring for different fish species. Great store.”
— Kiana Anderson5.03 months ago“I get my koi and water plants here as well as aquarium fish they are the best in Northern California”
