About
Aquarium Guy LLC is a freshwater and saltwater aquarium store in Louisville, Kentucky, run by Brian, a hands-on aquarium professional whose years of experience and genuine passion for the hobby show up in every build. 7-star rating across 46 reviews, the shop has earned a reputation for custom tank setups, plumbing, conversions, and the kind of personalized, knowledgeable service that's increasingly hard to find. On the retail side, the standout is the coral selection.
Multiple reviewers praise the excellent, vast assortment of corals for sale, making this one of the better spots in Louisville to shop for reef livestock in person. Alongside the corals, you'll find a solid inventory of saltwater fish, so reef keepers searching for corals or saltwater fish for sale near me can browse, ask questions, and get real guidance before they buy. The store shares space with Andy's Pet Shop, which carries parakeets, birds, and other animals, giving the location a lively, diverse feel.
Brian's deeper specialty is complex installations. One customer described how he replumbed a used 210-gallon tank, transferred an existing freshwater setup, and converted a 150-gallon into a new saltwater system — all in a single day, on budget, with no schedule changes. From initial consultation and phone troubleshooting to in-home installation, ongoing tank maintenance, and tank cleaning, he and his partner PJ handle the full process, including large builds of 150 gallons and up.
Pricing is fair and transparent, with no surprise charges. What sets Brian apart is his willingness to teach. He doesn't just set up a tank and walk away — he explains each step, repeats information when needed, and helps newcomers understand the hobby, which makes this a genuinely beginner-friendly aquarium store.
One customer who relocated from Texas with no local contacts found in Brian a real partner; another credited him with patiently walking them through their first tank cleaning over the phone. For Louisville aquarists looking for corals, saltwater fish, or an expert to handle a full freshwater or saltwater build from plumbing to livestock, Aquarium Guy LLC is a knowledgeable, service-driven fish store worth a call.

Customer reviews
“Awesome very knowledgeable”
— Brittany Davis5.02 weeks ago“They let me swim in the tanks! Not much fish poop.”
— Lee McWhorter5.0a month ago“First off, I moved here from Texas and have absolutely no contacts in Lousville, KY that could help me with my pretty complex "ask". Brian was there without any hesitation. Also was privileged enough to meet his bud, PJ who helped install. The ask: I have a 150 gallon freshwater and an empty 210 that I bought used. It was previously plumbed but wasn't sure on all of the needs to get it running again. Brian quoted me a very fair price and came to do the job (zero schedule changes) and got it done within one day without a penny of a price change despite the hoops we had to jump through. Essentially, the project was to move the freshwater setup/fish into the empty 210 and have it re-plumbed and make the 150 freshwater a new saltwater setup. Brian did this with flying colors and at a rapid pace given his years of experience. Further, Brian truly loves what he does and wants to teach those around him willing to learn. I expressed to him that I want to absorb as much as I can and I can feel that enthusiasm in his voice when he talks about this hobby and just know that if you have made it this far and are considering Brian (The Aquarium Guy) to setup your tank(s), you will have not only a setup but a lasting setup custom-fit to your needs only possible due to his experience and knowledge. Brian is an encyclopedia of aquarium knowledge and I can tell you that we encountered scenarios during my install that puzzled me for a minute but Brian pushed us to the finish line not just to get it done but to get it done CORRECTLY. These fish won't just survive, they will thrive. Lastly, Brian isn't done when the job is complete. He treats your tank as if it is his own and opens your mind to all sorts of possibilities and enhancements that you are able to do with your setup and I really appreciate that partnership because this is a hobby where a lot of jargon is used and very niche. Thank you again Brian and I am happy that we have crossed paths. Shout out to PJ too, you are the man! - Marc Johnson”
