Worlds Under Water

Worlds Under Water has built a devoted following across Northwest Arkansas, drawing customers from as far as Van Buren and beyond — some driving two hours past other fish stores just to shop here. Located in Fayetteville, this saltwater and freshwater specialty shop earns its reputation through crystal-clear aquariums, healthy livestock, and a staff that genuinely lives the hobby. The saltwater side is a standout, with vibrant corals, anemones, and a range of reef fish displayed in gorgeous tanks that double as inspiration for your own setup.

Longtime saltwater customers report fish still thriving years after purchase. The freshwater selection runs deep as well — cichlids, neons, guppies, angelfish, catfish, gobies, and even a super red Oscar that one customer scored at a great price. Live plants get consistent praise for their quality and variety, and the shrimp selection has earned trust with buyers reporting zero losses on purchases of 16 animals.

Stephen Beard and Brandon are the names you'll hear most from regulars. Stephen handles tank maintenance for both offices and homes, servicing saltwater setups twice a month and freshwater tanks monthly. One customer credited him with saving a freshwater tank that had been a disaster under someone else's care.

He also fielded a phone call about axolotl water quality from a customer referred by a local exotic vet — the kind of specific, practical knowledge that sets this shop apart. The store itself is meticulously clean, with display tanks that showcase what's possible and stock tanks that reflect genuine care. Thursday is apparently restock day, and regulars advise getting there early since popular items sell out fast.

Prices are consistently described as reasonable, which only sweetens the deal. A handful of reviewers noted occasional lapses in customer greeting, which is worth mentioning given the store's otherwise strong service reputation. But the overwhelming consensus from over 500 reviews is clear: for fish, corals, plants, and aquarium expertise in the Fayetteville area, Worlds Under Water is the destination.
