Owner Shawn, a marine biologist by training, has built a reputation among local reefers for his deep expertise and hands-on approach. Whether he's diagnosing a brown jelly outbreak and nursing a tank back to health in two days, or building a custom 80-gallon shallow reef plumbed to a 20-gallon mushroom tank, Shawn treats every customer's system like it matters. The coral selection is the main draw. Reviewers consistently praise the variety and quality, noting that Cardinal skips the overpriced "brand name" coral trend in favor of genuinely beautiful pieces at fair prices. If you're stocking a saltwater reef tank, the inventory of corals, marine fish, and invertebrates is substantial for a shop this size. They also carry a solid lineup of dry goods, including Bulk Reef Supply products, so you can grab essentials without ordering online. Tank maintenance is a cornerstone of the business. Shawn personally services clients' home aquariums on a regular schedule, and multiple reviewers say their tanks have never looked better than under his care. He's also helped newcomers from their very first fill-up through stocking, offering patient guidance without sales pressure — a detail that comes up again and again. Staff member Jamie draws her own loyal following, with customers specifically visiting on Sundays for her expertise and customer service. The whole team reflects that same ethos: knowledgeable, patient, and genuinely invested in helping people succeed with their reef tanks. Cardinal Aquariums is also expanding, with plans to double showroom space, add freshwater options, and increase operating days. For Clearwater's saltwater community, this shop has already earned serious loyalty — and it's only getting bigger. ## Specializations - **Water Types**: Saltwater, Freshwater - **Livestock & Products**: Corals, Reef, Dry Goods, Invertebrates - **Services**: Tank Maintenance, Tank Setup, Consultation, Custom Tanks - **Known For**: Knowledgeable Staff ## Highlights - Owner Shawn is a marine biologist who personally builds and maintains customer reef tanks - Extensive coral selection at competitive prices without inflated 'brand name' markups - Carries Bulk Reef Supply products alongside a solid dry goods inventory - Staff member Jamie draws dedicated Sunday customers for her reef expertise - Expanding showroom, adding freshwater options, and increasing hours to five days a week ## Brands Carried Bulk Reef Supply ## Customer Reviews **"Shawn Phillips"** - 5/5 - Edited 2 months ago > Nice selection of coral and coral needs **"James Whelan"** - 5/5 - Edited 5 months ago > Super knowledgeable staff and a great vibe.

The owner takes extra special care of your needs. He is marine biologist, he and his wife. Their education is reassuring that you will get what you need, in products and love stock. Also Shawn completes my saltwater tank maintenance, I have had others complete tank maintenance but I can tell you my tank has never looked and thrived like it does presently. Stop and check it out you won't be sorry. Iam still with Cardinal aquarium Shawn built my newest system 80 shallow gallon and 20 gallon mushroom tank plumbed together. I cannot say enough good things about the care of my tanks are given by Shawn. Some of my beautiful corals have came from the store. ## Nearby Stores - [Suncoast Aquarium Inc](https://www.fishstores.org/florida/clearwater/suncoast-aquarium-inc) - Clearwater, FL - 4.7/5 - [AJ's Aquariums LLC](https://www.fishstores.org/florida/gulfport/ajs-aquariums-llc) - Gulfport, FL - 5.0/5 - [Aquarium Reef Illusions](https://www.fishstores.org/florida/orange-city/aquarium-reef-illusions) - Orange City, FL - 5.0/5 - [Heeeere Fishy Fishy](https://www.fishstores.org/florida/gainesville/heeeere-fishy-fishy) - Gainesville, FL - 5.0/5 - [Hydros Aquatics](https://www.fishstores.org/florida/miami/hydros-aquatics) - Miami, FL - 5.0/5 - [Rainbow River Aquatics](https://www.fishstores.org/florida/port-st-lucie/rainbow-river-aquatics) - Port St. Lucie, FL - 5.0/5 --- *Source: [FishStores.org](https://www.fishstores.org/florida/clearwater/cardinal-aquariums)* *Last updated: February 7, 2026*
