About
Aquatic Technology in Columbia Station, Ohio has earned a reputation as one of the state's premier saltwater fish stores, drawing hobbyists from Columbus, Wooster, and well beyond — some making two-hour-plus drives just to browse the inventory. Owner Greg and his son Greg Jr. run this dedicated marine shop with decades of hands-on expertise, and the livestock selection reflects that commitment.
The store carries a massive range of saltwater fish, corals, and invertebrates, including seahorses — a genuinely hard-to-find species that multiple reviewers specifically traveled to purchase. There's also a beloved resident known as Mr. Grinch that visitors call a must-see.
What sets Aquatic Technology apart is the depth of knowledge behind the counter. Greg Sr. has been known to research parasitic isopods on stingrays, administer anesthesia for safe removal, and refuse to sell any fish he doesn't feel confident is healthy and eating well.
That kind of care translates into livestock quality that customers consistently praise — healthy, vibrant fish and corals that survive the transition home. For newcomers setting up their first saltwater tank, staff like Katie have been singled out for patiently walking through every question. The store stocks a solid array of dry goods, equipment, and supplies alongside the livestock.
Outside, a greenhouse area houses large plant tubs and even breeding cardinal fish — an unexpected bonus that delights visitors exploring beyond the main showroom. Greg also keeps a collection of vintage aquarium books in the back, which he's been known to share with interested customers. The atmosphere is more working fish house than polished retail showroom, which some visitors love and others find rough around the edges.
A handful of reviews mention inconsistent customer service or feeling overlooked, though the majority describe Greg and his team as welcoming and generous with their time. For serious saltwater hobbyists in northeast Ohio looking for selection, healthy livestock, and real expertise on topics like carbon dosing, acclimation, and quarantine protocols, Aquatic Technology delivers.

Customer reviews
“Made a trip to this store today. Great selection of fish. Owner was very helpful and friendly.”
— B French5.05 days ago“Fortunate to have this store near me. Everyone is helpful and there is a huge selection. This is the only store I buy my saltwater fish from.”
— scottoftheadam5.0a month ago“Greg and his son both are extremely knowledgeable about the hobby both at the entry level and the extreme enthusiast level; while seeking advice regarding carbon dosing, acclimation and quarantine, I spoke with Greg Sr, who invited me to look at the sting ray they were treating that had some form of parasitic isopod. He extensively researched the type of parasite, stages of infection and risks for removal, before leveraging a form anesthesia and freshwater dips to safely remove the parasite. I also have had multiple experiences with fish I wanted to purchase that had a rough time in shipping, or came in skinnier than expected. Greg always ensures the fish that go out the door are healthy and in good condition. He won’t sell a fish he doesn’t feel confident in. I’ve never had a doubt in the years we’ve been coming here, and for my family, that timeline spans decades.”

Ive been to several stores all over Ohio looking for Seahorses for a few years and this place actually has them in stock and sells them! I assume the guy that was helping us was the owner, super nice guy!! We made a 2 hr one way trip there and definitely wasn't disappointed at all!! Can't wait to return!”

— John Hammond5.08 months ago“Was in the area and went with my son. No "Hello" or "Can I help you find something" or any other type of acknowledgement that we even existed. Tanks are dirty, corals are basic, store is a mess. So we drove to Macedonia and I spent my money at a different store.”
