    I drove all the way from Sacramento to Ocean Aquarium in San Francisco specifically to purchase live freshwater fish. I arrived at 5:50 PM, fully ready to spend a few hundred dollars, only to be told they were closed -- even though their posted hours say they close at 6:00 PM. The staff made no effort to assist me or even acknowledge the fact that I had traveled a long distance and came prepared to make a serious purchase. Instead, I was turned away right at the door. This was my first time here, and unfortunately, it will be my last. I support small businesses when they value their customers -- but this was just flat-out poor service. If you're serious about buying quality fish and being treated with respect, I'd suggest looking elsewhere.

    All I can say is the owner is legit knowledgeable on fresh water aquarium . Amazing fish, shrimp and snail options. You will also go home with the right tools to adapt your fish to your own aquarium! Superb!

    This store is fantastic! The staff is super informative and helpful, and all of their fish look healthy and happy. We were actually visiting from out of town for a Giants game when we decided to buy a betta fish. Even though we had a 3-hour commute ahead of us, the owner went above and beyond to make sure we were prepared. She gave us detailed instructions, demonstrated exactly what to do, and even provided the proper tools to ensure our new little guy could be safely acclimated to my tank at home. We made it back safely, and our betta is doing great. I love this place and will definitely be coming back!

    my newest fish, soooo cute

    After years I got my second fish, I love my fish. The owners are still super nice and knowledgeable as always. Come here for fishy :)

    This place is such a unique place to visit, whether you are interested in fish or not. It's a mom and pop shop run by these 2 wholesome and kind individuals who've ran this place for almost 40 years. This place has so much history and character behind it, from the art pieces on the walls, to photos of the family themselves. My brother has been here multiple times and praises the place every occasion he gets. It was my first time going so I wanted to see what this place was about. The entrance is located along an alleyway and a fairly small location, but once you enter the store, you are surrounded by multiple fish tanks every turn. They've even gotten creative with a few tanks used for some of their fishes (e.g. the iMac monitor). This is the owner's hobby and it's so wholesome to see how much you can accomplish when you love something so much. So happy for these people and wish them all the best

    Available fish food and supplies here !

    Great and beautiful selection of assorted aqua life ! The owners were very knowledgeable and helpful in every way! Very sweet owners . I'm new to the aquarium lifestyle so they were very patient with me as well. Will always be coming back for any equipment or fish in the future

    Been wanting to visit for over 2 years, a lot of good things heard and I was not disappointed at all! Both owners were amazing and were both super excited to show me their options. Although I am not new to the hobby they gave me some really useful tips on acclimating, feeding, and answered a question I had asked many places. You can tell they are proud of what they have going and that is amazing, prices for being in the city are not bad at all. Their selection is amazing but came here for their goldfish. Left with a broadtail Ryukin. I will def come back even though I do not live near by !

    This is a long-standing, reputable family business, so they know what they're doing (which they should; they've been doing this for a long time). They have many, many tanks, mostly small and filled with little brilliant gems of fishies, and a good amount of supplies. I have bought fish and supplies, and acquired useful aquarium advice, from Jason since before he was at this location. Ask them questions! Parking can be a bit of a challenge (I usually ride my bike), but stopping in is worth it if you love keeping fish--or even just looking at them!

    A great learning opportunity, no hard sell! Justin Hau is all about a naturalistic tank set up before adding fish and plants.

    Took the drive 2 hours away to Ocean Aquarium off Cedar St. San Francisco Glad I got a chance to visit this old school Aquarium owned by Justin/Ady ----friendly old couple It is true all their tanks are planted with lush green plants & dirted/gravel substrates. They specialize in smaller schooling fishes, no aggressive fishes. Although they are very friendly, they must charge Premium prices to keep this store running. I bought 2 really small puffers $45 each, 1pair of electric ram @ $35, water crest, java fern Total $180 Cash...Very Pricey to me compared to any other bigger Aquariums. Justin is or sounded very knowledgeable with water parameters & tips with fish/plants. The main parameter per Justin is the correct PH of 7.0 for healthy fishes not nitrate/nitrite. I will take his advice & monitor the health of the fishes I bought. Overall, a nice visit to experience his long standing business.

    Outstanding customer service!…read more I've purchased aquarium equipment from many stores over the years, and Aqua Forest Aquarium has been one of the best experiences I've ever had. Steven took the time to call me personally, answer my questions, and make sure my order was the best fit for my setup. Throughout the entire process, he went above and beyond to make sure I was happy. Everything arrived safely, was packaged extremely well, and the entire experience was seamless from start to finish. They resolved a situation in a way that far exceeded my expectations, and I'll never forget their kindness. I've recommended Aqua Forest Aquarium to many fellow hobbyists, and every one of them has shared positive experiences as well. It's rare to find a company that genuinely puts customers first. Thank you, Steven and the entire AFA team. You've earned a lifelong customer, and I highly recommend Aqua Forest Aquarium to anyone passionate about planted aquariums.

Step inside this specific room, though, and the world pivots on its axis. It is the low, mechanical hum of the aerators that gets you first. A steady, rhythmic thrum--the heartbeat of a hundred tiny, artificial oceans packed into glass boxes. There is something deeply, almost subversively soothing about it. It's a sensory clean room, a brief reprieve from the exhausting, hyper-caffeinated hustle just outside the door. You stand there, bathed in that eerie, neon blue light, watching the neon tetras and the aggressive, territorial marine life dart back and forth. They aren't thinking about the rent or the rising tides of the city; they're just waiting for the next pinch of flakes, the next fresh catch. If you're lucky, you get the freaks and the anomalies--an octopus lurking in a PVC pipe, a restless eel, or today's prize, a lone turtle, gliding through its own miniature universe with a slow, stoic indifference that borders on Zen. This isn't a trendy pop-up or a sleek, minimalist boutique designed to part tech bros from their equity. This place is an anchor. It's been sitting right here, largely unchanged, for 40 years--an absolute eternity in a city that eats its own history for breakfast. It doesn't change, it doesn't apologize, and every time you walk through that door, it brings you straight back to an even keel. In a world where everything beautiful eventually gets paved over or corporate-approved, you look around at the salt-stained glass and the bubbling water, and you think: Thank God. I'm just glad they're still here.

    I contacted Cesar for a "custom" set up including base stand, basking condo, and filtration system…read morefor a 5-year-old red eared slider turtle. I could have saved a lot of money (and time after the results) if I had purchased everything myself with tips from turtle forum sites and YouTube DIY videos, but I was willing to pay for a "professional" to have peace of mind and support a local small business. While Cesar was nice and knowledgeable about general tanks and filtration systems, the outcome of what we received shows that he is not an expert on what turtles fully need- he's more a filtration and fish expert as shown mostly on his website and Yelp photos. The setup we received was not adequate and required extra money (over 2k) to fix cosmetically and functionally for us to have good access from the basking condo to the tank. Let's start with the pricing issue. I had called Cesar to get some ballpark figures which he had provided with a guess. But when the final quote came ... it was around 1k higher than the ballpark pricing (a big difference!). Knowing the new higher prices, I still contracted him to help me since I wanted an expertly set up and permanent home for our 5-year-old red eared slider. Cesar presented himself as a knowledgeable trustworthy professional. The base stand was the first to arrive (about a month after deposit was paid). Please note that we never told Cesar to do a rush job as we were more focused on moving into a new home at that time. The base stand was about 40% of the total cost. He provided photos of the stand prior to delivery, and I approved it by looks only. When the stand arrived, it did look like the picture, but it seemed very basically put together despite Cesar's claim that the manufacturer said it was polycoated to help with waterproofing. I knew it wasn't stained since I didn't want to change the color. At that time, we had a contractor on site at our new home for remodeling who looked at the stand and confirmed that this was an incomplete unfinished product, with the front portion being anything of quality and purely cosmetic. Upon arrival, the stand had doors that did not open properly. The magnetic closures for the doors were cheap and crooked. The top and back was just plywood. The back and inside had many splinters and open drill holes. The overall wood was not smooth to touch and did not seem it was coated enough to be considered waterproof. Please see provided photos and note that the photo Cesar posted himself on Yelp on Sep 24, 2021, is NOT an accurate depiction of the quality he provided us. The blue stand pictured in his photos was AFTER our contractor spent 3 whole days having to sand down the door and paint it blue. Had I known the door would have been that big of an issue, I should have let the manufacturer fix it prior. But overall quality of the stand would probably have remained the same. The door would have been just rotated to match the grain, which would have caused less work for our contractor, so that part was my fault. During our initial complaint (before we put our own contractor to work), Cesar said his manufacturer was willing to fix it but at that point we didn't trust them to do so since there were many issues we had complaints about. To add fuel to our fire, Cesar initially claimed that he did not use his regular guy for the job (why did we get a 2nd tiered manufacturer when we paid the same rates as others) and later said this guy also does stands for him all the time. Then why did ours come so incomplete compared to what he shows online? After our initial complaint, Cesar did help us discount us a few hundred dollars but ultimately it wasn't enough to justify the amount of money spent after our contractor worked for days to make it right. However, we tried to be a good sport and continued to entrust Cesar to complete the rest of the contracted turtle filtration system and basking condo set up. When the condo arrived and filtration was set up, we were so excited to be able to transfer our red eared slider into his new larger home. The condo itself is good quality in materials but was not a custom structure. At first, we did not notice any issue with the condo but contacted Cesar after a few days. The ramp length was a bit short, and our heavier, older red eared slider turtle had a lot of trouble pulling his weight up to get on top to bask. This will only get worse as time passes and he grows larger, and turtles should bask comfortable daily for their shell health. The other issue was that we could not get our arms into the tank to move anything around which presents a HUGE ISSUE FOR SAFETY. It is also not easily able to be lifted off during emergencies. If you research custom turtle basking condos in forums, you will find that the ones that sit on top of the tank are mostly 50% in length so that you can still place your arm inside the tank to clean/move things around or perhaps save your turtle if stuck. Or the ones that have a full 100%
