Healthy Fish and Aquatic Plant Sales: They are known for having "very healthy fish" and "decent plants." This includes various species suitable for home aquariums, ensuring customers receive robust and thriving specimens. The emphasis is on quality and vitality, reducing the common issues of sickness or stress often associated with newly acquired fish.
Aquarium Set-Up Guidance: For beginners, they provide crucial advice on setting up a new aquarium, including recommendations on tank size, equipment, and initial preparation. They actively guide customers away from common pitfalls, such as the challenges of maintaining very small tanks.
Water Parameter Education: A core part of their service involves educating customers on vital water chemistry concepts, such as pH levels, ammonia levels, and the importance of proper water conditioning. This foundational knowledge is essential for long-term aquarium success.
Water Testing Services: Ocean Aquarium offers a unique and invaluable service where they request customers to bring in a water sample from their conditioned tank before selling them fish. This ensures the tank environment is safe and stable, maximizing the chances of the fish thriving. This commitment to pre-sale vetting highlights their dedication to animal welfare.
Comprehensive Tank Care Instructions: They provide detailed explanations on ongoing tank care, including maintenance routines and strategies to maximize success in fishkeeping, even for challenging setups like small tanks.
Supply Recommendations: Based on individual tank size and specific needs, they advise on and sell the necessary supplies, ensuring customers have the right tools for water conditioning, filtration, and general maintenance.

Commitment to Fish Welfare Over Immediate Sales: This is perhaps their most remarkable highlight. The willingness to refuse a sale to a customer who isn't prepared to properly care for a fish (as demonstrated by the 5-star review from the couple with the 2.5-gallon tank) showcases an extraordinary ethical stance. They prioritize the long-term health of the animals, ensuring pets don't "accidentally die" due to owner inexperience. This is a rare and highly commendable practice in the retail world.

They patiently explain complex concepts like pH and ammonia levels, guide customers through the conditioning process, and even require water samples to pass a test before selling fish. This level of personalized education is invaluable for ensuring customer success and animal thriving.

Long-Term Customer Success: The "Edit" in one review, detailing the successful return and purchase of thriving fish and plants after following the owners' advice, serves as powerful proof of their effective guidance and the positive outcomes for their customers' aquariums.
Holistic Approach to Aquarium Keeping: They recognize that simply having a tank and fish isn't enough. Their focus on the entire ecosystem – water parameters, plants, and ongoing care – ensures that customers are set up for genuine, sustained success in the hobby.

Ocean Aquarium Reviews
The friendliest and most knowledgeable couple own this aquarium store. They have everything you could ask for, and really know their plants and fish. I highly recommend for anyone trying to get into the hobby. I bought my tank, and a handful of supplies from them, and will be back for more. Just got a hill stream loach and he’s thriving.
May 29, 2025 · SonnyMy husband and I just visited today and they wouldn't let us buy a fish! So, why the 5-star review? Because we clearly didn't know what we were doing, we needed education, and this lovely couple took their time explaining pH, ammonia levels, and water/tank care. Before shopping for fish, we had made the mistake of buying a small, 2.5 gallon tank, which we learned is harder to care for than a large one. The couple at Ocean Aquarium asked us to consider a larger tank, but this small one is all that we can fit in our apartment. So, they patiently explained everything we'd need to do to maximize our chances for success. They set us up with the supplies we need to condition the water over the next month to prepare for fish and plants. They told us to bring them a water sample in a month and, if it passes their test, they'll sell us fish and plants. We loved how passionate they are about their craft and their fish. While we were disappointed that we couldn't get our fish today, we really appreciate the time they spent with us to ensure we didn't take something home today just to accidentally kill it. Besides, we now have a little knowledge and we can enjoy the next month learning more and preparing our aquarium.Edit: After a little over a month of conditioning our tank, we just went back, passed the water test, and got our fish and plants! So far, they're thriving. We really appreciate the knowledge that the couple at Ocean Aquarium spent time giving us.
Mar 24, 2025 · Jerry RyleOld school fish store, but in a good way. This place will not win any awards for an orderly selection of fish and hardware. But they have an unbelievable selection. I also gets such invaluable hints when we discuss my tanks. I've changed my daily regime because of the advice I got. Now my tanks lot great. Incredible selection of Beta's. I go to the store monthly just to see what is new in their livestock. Always something new of interest.
Jun 22, 2025 · Bruce OlitzkyThe owners of this shop are incredibly knowledgeable and kind people. It is an eclectic collection of very well planted, self-sustaining tanks which is a testament to the owner’s knowledge. Very few have running filters because very few if any need it. Prices are very reasonable and they have things that can be hard to find, e.g. unusual fish tank form factors, large live rock, etc. The only downside of this place is its location. Highly recommend taking public transit to get there. There’s a bus stop a block away, but no parking is nearly impossible.
Jun 25, 2025 · Alex S (Nathanaxe)Just went here from my first time and let me tell you I usually don’t do reviews but I just had to I left with so much knowledge that I thought I knew and things that I thought I was doing right and was doing it completely wrong. this place is amazing. The fish tanks are incredible. The prices are amazing. I love it. I can’t wait to revisit. Thank you for everything you taught me today.
