About
7 Seas Tropical Fish is a family-run fish store on South Gaffey Street in San Pedro, California, with freshwater and saltwater fish for sale alongside a big floor of new aquariums. The shop bills itself as Southern California's largest aquarium showroom, and its own page lists exotic and rare freshwater and saltwater fish, invertebrates, corals and freshwater plants. Brothers run the business today, and longtime customers describe it as family owned and operated.
Livestock covers both water types. A March 2026 reviewer called the range of exotic freshwater and saltwater fish incredible and said the staff clearly know how to keep specimens healthy. A Spanish-language review the month before praised the same wide variety of both.
Another recent shopper left with a sailfin pleco and a jar of pleco wafers. Earlier reviews mention snails and fish that stayed healthy at home, and one reviewer rated the store above the Aquarium of the Pacific. The equipment side is what sets this aquarium shop apart.
That same March reviewer said they had never seen so many new tanks in one place, from small starter aquariums to large display tanks, along with filtration, lighting, decorations and supplies. The store's own posts feature aquarium lines from Red Sea, Innovative Marine, JBJ and Ultum Nature Systems, and fish food and everyday supplies are available too. Beyond retail, 7 Seas offers aquarium installation and service.
In June 2026 a customer came in to replace a fountain pump and was instead shown how to clean the old one, which then worked. Reviewers often describe the family and staff as knowledgeable and quick to help with questions, and some say the owners take care to source livestock ethically. Price is the recurring complaint: several reviewers say 7 Seas costs more than other shops, and a few felt the sales pitch or the advice came across as pushy.
Others are glad to pay for same-day, in-stock purchases and hands-on guidance. For saltwater fish, corals, plants or a complete new tank setup in San Pedro, CA, 7 Seas is, as one regular put it, worth the drive.

Customer reviews
“I went in today to replace a fountain pump, ready to pay whatever since I have no idea what I'm doing. They kindly told me how to clean up what I have to make it work! And it worked!! I used to have aquariums and this was my go to spot then as well. You just don't find honest integrity in businesses so much any more. THANK YOU!”
— Lo R5.04 days ago“Cool store, but ridiculously over priced. I guess the main clientele are from PV and don't care about being ripped off. 15 dollars for a silver dollar when you can get the same fish for 6 at other stores. I only went because I needed a specific pleco and the person who answered the phone claimed to have "all the good stuff". Yeah it's a nice assortment, I'll give you that, but I don't appreciate being talked down to. The owner was critiquing how I was going about I was cycling my tank and brushing it off as "that internet stuff." He then mentioned several times how he's been keeping fish since the 80's I respect that but I'm sure a lot has changed in terms of what we know in the last 40 years, man. In the end it was $40 for a basic sailfin pleco and a little jar of pleco wafers. Probably will not return, a lot of better stores towards Long Beach and OC.”
— Roman A2.03 months ago“If you’re serious about aquariums, 7 Seas Tropical Fish in San Pedro is simply the best fish store around. They might not always be the cheapest, but what you get here is on a completely different level than most aquarium shops. The selection of truly exotic freshwater and saltwater fish is incredible, and the staff clearly know what they’re doing when it comes to maintaining healthy, high-quality specimens. What really blew me away is the massive selection of brand-new aquariums, tanks, and accessories. I’ve never seen so many tanks and setups in one place — everything from small starter aquariums to large display tanks. The amount of equipment, filtration systems, lighting, decorations, and supplies they carry is honestly bigger than what I would expect to see even in a catalog. If you’re building a new aquarium or looking for rare fish you won’t find at big chain pet stores, this place is absolutely worth visiting. It’s easily one of the most impressive aquarium shops I’ve seen anywhere.”
— Green Wave5.03 months ago“Exelente lugar demaciada variadas tanto ejemplar de agua dulce como salada”
— MIKE VALDEZ5.04 months ago“Top notch place! Small business has been in business for years! The family has been very helpful in sharing their knowledge. They don't push hard sales. Pricing is high when you compare to online for products and merchandise however I am happy to pay for in stock same day purchase with many open hours often to 8 PM. The fish are healthy and clean. Lots of sizes and both fresh and salt water species. I will be going back for all fish food and supplies.”
— Jonathan Anderson4.02 weeks ago“Haven’t found another one like it they always had the fishes I wanted or didn’t and ended up taking home stuff just cus they had such a wide variety it’s worth the drive imo”
— Omar F5.03 weeks ago“The ideal fish store imo. I’ve been several times and every visit is helpful and inspiring. I trust the owners and employees they care about ethically sourcing and caring for their livestock and are always happy to help with questions!”
