About
Tucked into an easy-to-miss Portland storefront, Woody's Seahorse Aquarium & Supply opens into a color-drenched world that regulars describe as magical. This is a saltwater-only aquarium store, and that focus shows in every tank — pristine displays brimming with SPS, LPS, and soft corals, plus the giant tubs of genuine, high-quality live rock that reef hobbyists increasingly struggle to find anywhere else. If you have searched for healthy corals or saltwater fish for sale in Portland, OR, this is the shop reviewers keep naming as their favorite.
The shop is run by a tight-knit, deeply knowledgeable team — Terry, Tewsley, and Bret come up again and again. One recent visitor called it the best reef aquarium store in the Portland area, praising how organized it stays while still feeling like a casual hobbyist hangout, with a vast selection of livestock and dry goods packed into a small space. Another credited Tewsley with patiently answering every technical question and special-ordering the exact fish he needed to finish his tank.
When a biologist came in puzzling over how to house Chesapeake blue crabs for an experiment, Terry talked her through it — proof of how far this crew will go. Beyond corals and fish, you will find seahorses, well-stocked cleanup-crew invertebrates, and cycled live rock ready to go, along with the tools and liquid additives that day-to-day reef keeping demands. Comprehensive API water testing runs $10 and covers nine parameters — salinity, alkalinity, calcium, magnesium, nitrates, nitrites, phosphates, pH, and ammonia — with results emailed so you can track trends over time.
An RODI and saltwater filling station out front makes topping off painless. What sets this Portland aquarium store apart is its culture. First-time reefers, parents with toddlers, and seasoned hobbyists chasing rare corals all report feeling genuinely welcomed rather than pressured.
Staff will explain macroalgae to a four-year-old or talk you out of a fish that will not thrive in your system. For anyone keeping a reef tank near Portland, Woody's is a true local resource.

Customer reviews
“This is by far the best and my favorite reef aquarium store in the Portland area. While organized and well-kept, it still feels like a casual hobbyist hangout and super approachable. The displays are excellent and the selection of livestock and dry goods vast for such a small space. This was the first business of any kind I’ve ever been in in Portland where I felt genuinely acknowledged and appreciated, not only as a customer, but also simply as a human being. My interaction with one of the owners and another employee today was a lot of fun and motivated me to get back into the reefing side of the hobby after a few years doing freshwater.”

— Егор Егоров5.02 months ago“I recently had a fantastic experience at Woody's Seahorse Aquarium and Supply, largely thanks to Tewsley’s exceptional service. She was incredibly knowledgeable and took the time to answer all my technical questions without ever being pushy or rushing my decisions. I was especially impressed that she was able to custom order the specific fish I was looking for to ensure my tank setup was perfect. The level of care and expertise here is hard to find, and I’ve definitely found my new favorite shop.”
— Serge Bondarchuk5.03 months ago“This is an awesome aquarium shop! I came in to brainstorm how I could keep Chesapeake blue crabs for a few weeks while conducting some biology experiments and they were beyond helpful. Terry really knows his stuff. Everyone was incredibly welcoming and supportive. I will definitely be going back for all my saltwater aquarium needs!”

— Michael Tran5.0a month ago“I started a seahorse tank with the help of the owners. They are super helpful and really care about their fish. I can trust that their stock is well cared for. I go in sometimes kinda in a panic because my phosphates get high and they always help me problem solve. They are very responsive to customer needs. They have the experience needed to give informed advice. Their tanks are amazing! I hope you decide to go visit to see them!”
— Melissa Harrison5.02 months ago“I highly recommend everybody David at Woody's aquarium they offer all your equipment needs for both salt and freshwater they also offer maintenance on your home tank 10/10”
— John C Kasziewicz5.02 months ago“Visited the shop last week and had a wonderful experience. I brought my four-year-old with me, and the staff were amazing — they didn’t just try to sell me something, they really took the time to make us feel welcome. They explained everything clearly, even took the time to talk with my son and show him what macroalgae are! The whole visit felt personal and friendly. The staff are extremely knowledgeable, the coral selection is fantastic, and the prices are some of the best I’ve seen. This is a great place to shop if you’re looking for healthy fish, beautiful corals.”
