About
Tucked away in Sioux Falls, South Dakota, Sioux Falls Aquatics has built a devoted following among reef keepers and saltwater enthusiasts — and for good reason. Owner Matt has turned this compact shop into what many regulars call the best saltwater destination in town, with pristine display tanks, a huge rotating selection of corals and frags, and consistently healthy livestock that customers rave about months after purchase. The saltwater side is clearly the star here.
Reef hobbyists will find everything from live rock and quality frags to specialty foods like LRS reef food, along with the dry goods, equipment, and salt mixes needed to keep a thriving reef tank. Matt's deep knowledge of reef systems gives newcomers the confidence to take the plunge, and experienced reefers appreciate his ability to source quality livestock and provide honest, detailed advice. Freshwater isn't an afterthought, though.
The store stocks cichlids, angelfish, and community fish like neon tetras — one customer noted their neons were noticeably larger and more colorful than big-box alternatives. The freshwater frozen food selection is among the best in Sioux Falls, and specialized products like shrimp-safe plant fertilizers show that Matt pays attention to niche needs. You'll also find Seachem Prime at competitive prices, making it worth a stop even for a quick supply run.
Beyond retail, Matt offers tank installation and maintenance services, and multiple reviews mention his hands-on approach to servicing customer tanks. The store is small but immaculately kept, reflecting the same care visible in every display tank. Staff interactions feel personal rather than transactional — customers consistently describe feeling welcomed and well-informed after visits.
What sets Sioux Falls Aquatics apart in a city with several solid fish stores is the combination of pristine tank conditions, curated livestock quality, and Matt's genuine passion. If you're building or maintaining a reef tank in the Sioux Falls area, this is where the serious hobbyists shop.

Customer reviews
“definitely more of a reef tank store, if you aren't into cichlids the freshwater selection probably won't impress you. however they do have the best selection of freshwater frozen fish food I've found in Sioux falls so far. worth stopping in just to buy seachem prime, you'll get a better deal here than you will anywhere else.”

Really impressed with the high quality products in stock. For example, I purchased some specialized plant fertilizer safe for my shrimp tank. There is a huge selection of saltwater products! I only started with the hobby recently and only have freshwater now. But if I ever wanted to try a saltwater tank, this is definitely the first place I would go for supplies!”
