I have had aquariums for 33 years and over the years seen less and less options for buying quality, healthy and a good selection of fish. I found this place about a month ago, this place is a fish keepers paradise. The staff are very friendly with a mountain of information if you have questions. Almost every tank looks like a show tank. I can't wait to go back for my next visit. read more

Simply put, the very best aquarium store in the Seattle area, and quite possibly the universe. Staffed with rabid fish fanatics who know everything about anything fish related, this place is rapidly becoming the can't-miss mecca for freshwater aquatic hobbyists new and old. Seriously, go there. Do it now. Kill if you must. read more

This is just going to be another boring 5 star review. Blah blah blah, fantastic. Blah blah blah, super knowledgeable and helpful. Corey and his crew are awesome. Every time I go in they have some new aquatic life form which makes me consider seriously expanding my hobby. Fantastic selection, and great service too. Even if it is a bit off your beaten path, make the trip, especially if you are in search of new fish or plants. read more

The shop and fish are nice but prices are through the roof here. Getting there first thing I couldn't get help because they were still in the process of opening. News flash, you get your opening process done BEFORE YOU OPEN so when you open you can help customers who what to buy stuff from you instead of waiting for you to open,,,AFTER YOU OPEN! Business 101 kids. I did get there early and from my car watched as one of the employees wheeled a 44 gallon plastic garbage can out the front door and to where their curb met the parking lot, aaaaaaannnnddd, you guessed it, she poured the dirty fish water with all the excrement into the parking lot. There are tons of health risks in doing this to include Mycobacterium, Erysipelothrix, Campylobacter, Aeromonas, Vibrio, Edwardsiella, Escherichia, Salmonella, Klebsiella and Streptococcus iniae to mention a few. I only found this amusing because she indeed made you wear your mask totally correctly as well as taking your temperature before you walked in. Amazing right? read more

Hands down the best customer service in the fish store industry. The owner is willing to do whatever it takes to meet your needs including special orders, education, shipping, you name it. He is also highly supportive of the local community both by buying local when available and donating and participating in the local aquarium club. Add to that a quarantine period for fish prior to sale, a wide selection of high quality stock, and great husbandry practices, and you're pretty much guaranteed to have a beautiful, healthy stocked tank. The foods in stock are top quality and difficult to find in stores rather than online. Equipment available for purchase is all personally chosen after being tested in their own tanks or after intense research on other's experiences. Plants are algae-free and luscious. Hard to find products like Finnex LED lights, ceramic Pleco caves, seiryu stone, and manzanita wood are usually in stock...and if you follow them on Facebook and via newsletter you'll be privy to previews of new items and relevant articles. I drive an hour and a half through rush hour traffic just to support this epitome of fish store perfection. Seriously, GO THERE. You won't be disappointed. read more

Aquarium Co-Op is an amazing store, and Cory and his staff are as friendly and knowledgeable as it gets! He is a very real and down to earth salesman and has more than earned my dollar time and time again. Thank you for your amazing insight in aquatics and your undying passion for everything fish. 2 big thumbs up for Cory and Aquarium Co-Op! read more

The people were so helpful. I'm interested in buying a beta and the owner, Cory, was very educational about the correct way to care for a beta, the tank size he needs, who he can get along with, the best equipment, and about beta in general. I found I was told misinformation at a big box pet store, who of course don't specialize in fish. They only carry REAL plants, wood, and small hiding places for fish. He also carries live worms rather than freeze-dried and flakes for betas. They carry many different kinds of fish and aquariums. He also educated me on goldfish. He debunked some myths. He spent a good 45 minutes with me. I will definitely buy my aquarium needs here. read more

This place is the best. The staff is knowledgeable, friendly and helpful. They will spend time with everyone who comes thru the door and has questions or needs help. I will never go to another aquarium store. These people really love the plants and animals they sell and they really want their customers to be successful fish parents. read more

Great service and helpful! Even though I'm far from Washington state I sure wish I wasn't! They are helpful and great at answering questions or getting you what you need even if you're not right by them! I received my order yesterday and the catappa leaves are the best I've ever gotten. Their sponge filter have a nice weighted base that sits with great stability as soon as you put it in your tank! I watch Cory on YouTube every day. My day isn't complete without watching Cory everyday. read more

This place is great. So glad I found an alternative to the chain stores for freshwater supplies. Angelo spent a ton of time helping me convert my six gallon to a shrimp-only setup, answering all my dumb questions and giving lots of helpful advice. The store is clean & well-stocked, and the livestock is gorgeous. read more

I was back to Aquarium Co-Op again recently. This time not for aquarium fish but instead for koi and other pond gear and animals. I was really stoked that Cory knew so much about outside pools and the unique differences between indoor aquariums and having koi, goldfish, snails and others outside. I came away with the fish, snails and tubing I needed for sure but the information I learned was truly invaluable. My koi are going to have a much better summer thanks to the advice I got from Cory and his team. Definitely still recommend this place for aquarium fish but now totally recommend them for ponds as well. read more

Great, healthy selection! Due to COVID I have yet to go to the store in person, but I've made several purchases online. Plants are healthy and cool merch. Hopefully I can come in and shop soon, because the shipping fee is getting me. Mainly because I am indecisive and end up making several purchases over the course of a few weeks rather than buying them all at one time. Follow their app if you're new to the hobby. read more

I decided to start keeping a 10 gallon planted aquarium as a new hobby around Christmas time. I new next to nothing about aquariums, lucky for me I found my way to Aquarium Coop. Cory and his staff are very helpful and knowledgeable, they were patient with me and never tried to "sell" me. The prices are reasonable and the selection is great. read more

If you're into the hobby of keeping Fish, the Aquarium Co-Op is the place you want to be. I've been going to the co-op now for almost 3 years and I've never had a bad experience. I always get the help that I need, quality supplies, and friendly conversation with the staff and the customers. I really appreciate the fact that they take the time to quarantine their fish before they go out onto the floor for sale. They also have a huge selection of plants and the knowledge of how to be successful with them. Give them a visit and I promise you won't be disappointed! read more

This store is the best Aquarium store! Robert and Ally are so helpful to me and my family as we learn about the many fishes and how to care for them. We bought a large tank from Aquarium Co-op and have a lot of questions. Robert and Ally are knowledgeable, informative and so patience as we figure out how to care for our fishes. I highly recommend!! read more

I have not had the pleasure of visiting the store in person, but I have ordered online. After 3 orders from the Co-Op, I have been extremely pleased with the quality of the plants and equipment as well as the streamlined website and fast service. Not to mention all the help given via the YouTube channel and blog posts. As a newbie to the fishkeeping hobby, The Aquarium Co-Op is a vital resource for both information and products. I would give 6 stars if I could. read more

Excellent selection of tropicals for all tank sizes, healthy plants, decor, and awesome selection of Hikari foods. They have beautiful Discuss as well. Knowledgeable and caring (about the fish and customer) staff! read more

Found Cory through youtube and was so thrilled when I found out he was in WA. I make the 1 1/2 drive just to get my stuff from here. I've definitely made many trips to a lot of LFS in my area and all the ones leading up to get to Aquarium co op.. and none of them come close... if you want THE best quality fish and plants... you will shop here... I've never got a sick fish or plants that carried algae or anything else into my tank. read more

I have been watching Cory's videos for years but never ventured into the realm of planted tanks as I loved bare bottom tanks. Recently lost the last goldfish in the tank and was undecided on what to put in next. After watching more of his videos, the unboxing of different varieties, and the new warehouse video...I knew I was going to go planted. I have had two deliveries thus far. First was to get an idea on spacing but not everything I needed, the second filled in spaces. With both deliveries the process was great as I had emails when it was packed, shipped, out for delivery, and delivered. Each box is packed well to avoid damage and the plants are in a wet cloth like bag and inside a plastic bag to retain moisture more. All of the plants are doing great. I did start to get some brown algae and the videos were there to help as well. A few otocinclus later and the tank is clear as can be. Cory and the team are doing a lot for the hobby and I will be back for more as I need it. read more

Great staff, very knowledgeable.. every question asked was answered. Found the perfect tank and fish to go along with my new tank. Great place! read more

My favorite place to shop and learn about fish keeping. They put so much effort into being the best at what they do and in my opinion they are succeeding easy. The YouTube channel is my favorite to watch and listen to as well. So much to be learned from Cory and his employees! Appreciate them very much! read more

I discovered this gem via Yelp. The store staff is incredibly helpful and knows everything there is to know about their stock. You can just tell that the fish are healthy and happy here - each one is treated like a glittering jewel in a gorgeous tank suited to their needs. I am calling this the best freshwater fish store in the Northwest!! :) Totally worth the almost hour-long drive from Sammamish for their knowledge and awesome stock. Also, I highly recommend following them on Facebook because they post each week about what they have in. read more

First of all, Cory from Aquarium Co op is a fantastic person who deeply cares about the fish community. He goes beyond the limits of helping everyone with their questions. His store has an awesome collection of fish and aquarium products. Proud to say I'm a loyal customer. He also has a fantastic online store with super fast shipping. A perfect business with great customer service by far. read more

Overpriced items and crappy customer service! Ordered an LED from here couple months ago. They will not price match and gave me an attitude about it. Never again! read more

Nice selection and very friendly staff. Convenient inventory and added bonuses with purchase.

If you're looking for a local fish store, look no further! This store is clean, the staff is very informative and helpful and they have a great selection of fish, plants, and of course my favorite; shrimp! I will be frequenting this store to stock my shrimp tank. read more

This place has quality fish, accessories, plants, food, and equipment. The employees are very knowledgeable about caring for fish and plants. read more

Five stars for Murphy! We enjoyed visiting this friendly YouTube famous puffer fish fish with our family. Very nice staff and a good vibes kind of store. read more

One of the very best Aquarium stores in the Seattle Metro area for freshwater community fish and plants! they offer great products at decent prices. the LED lights, for example, are high quality and much less expensive than other stores. the new LED lighting now available in the industry has made it possible to have lush plant growth without all the heat and energy expense. the staff at aquarium co-op is very knowledgeable and the selection of fish is great! places like this are inspiring a new level of interest in aquarium keeping where it is now possible for a much more reasonable investment of time and money, to create a colorful and vibrant ecosystem of plants and fish that complement each other for lower maintenance and better health. read more

My overall experience with Aquarium Co-Op was 5 stars. Whether you're a newbie or a life-long fish hobbyist, this store has everything you need. Owner Cory not only has the healthiest fish, plants, food, etc., but he'll also send you home full of excellent advice on everything aquarium related. I learned on my last visit that Cory is very involved with the Greater Seattle Aquarium Society; he sincerely enjoys the hobby of keeping & breeding fish. read more

Aquarium co-op is the best fish-store in the Seattle area. Totally worth the 10 mile trip from the city. Cory, the super helpful owner helped me with some lighting equipment I was looking for and answered a lot of my questions. Clean, well lit and well-stocked store with the best assortment of freshwater fish and accessories. read more

I am so happy to have found this place. I was looking to stock my 300 gallon bowfront with freshwater plants, and Cory was amazing. He obviously has a huge passion for his customers, and his store. Very clean, great quality of fish and plants, and tanks are clean and healthy. Cory took the time to explain everything I needed to know about plants, his knowledge is unsurpassed. He went above and beyond to help me stock my tank. If you are a serious hobbyist and want to see an amazing fish store, take the time to visit aquarium co-op, you will not be disappointed. You are doing it right Cory! Wish you were closer! read more

Ali is always so helpful online. She answers FB questions promptly, has a great sense of humor and customer service, and if she doesn't know the answer, she finds the answer. Great bunch of people working there! read more

Aquarium Co-Op is the jewel of Edmonds. This store offers amazing freshwater fish, rare aquatic plants, top of the line aquarium supplies and phenomenal customer service. Aquarium Co-Op gives you the boutique experience without the boutique price. The owner is friendly, knowledgeable and willing to help customers source rare stock. I couldn't recommend this store more. read more

Great selection of plants for your planted aquarium. They also have glass inlet and outlets to make your aquarium look it's best

The owner is very knowledgeable and willing to share his knowledge. Quality fish, great prices and they're still expanding. It's really nice to have stores like this that specialize in the hobby. The store is nice and welcoming and there's lots to see. If you visit, plan on hanging out for awhile. read more

Order to delivery time can't be beat. I do need fish livestock and wished I lived closer. I wonder if a list posted on the website of current livestock availability would get me to drive in? read more

Nice Store, helpful staff. Nice plant selection. Fun to see some more unusual fish. Found everything I was looking for. Well worth the long trip from where I live. Love the YouTube videos! read more

Really disappointed. Great fish don't get me wrong, healthy, active, but customer service....not great. I just recieved oto's as a gift and really wanted to keep them healthy and well taken care of, so I thought who better to ask then the really great fish store of legend that they came from...right? Nope! I called them directly and asked what they had been eating previously. The guy who answered the phone appeared to be really inconvenienced by my call...for a store that proclaims such concern and stewardship for livestock, my concerns were met with neither compassion nor concern. He spoke so fast as to be unintelligible...I asked again....again same response. I then decided to ask if perhaps my question could be answered on the website. He quickly agreed and referred me to the website. Guess what?! No answer as to what to feed my oto's and or how! Have no fear! I will not let these fish die...lik the other 5 ember tetras and 6 cherry shrimp I got from them in November. Not casting blame on that one, just saying maybe they aren't so great. read more

Placed my first order and the customer service and shipping speed was fantastic! I would definitely urge anyone to buy from the coop, you won't be disappointed. And if you have any questions, Cory has most likely made a video on his YouTube channel that will throughly cover it. Cory has done so much for the hobby, and I greatly appreciate it. read more
