About
Treasure State Aquariums is the aquatic heart of Billings, Montana — a proper, independently run aquarium store that hobbyists happily drive in for, with some making the trip all the way from Wyoming for healthy livestock and advice they can actually trust. " Freshwater is the backbone of the shop. You'll find bettas, kuhli loaches, shrimp, goldfish, and community-tank staples for sale in Billings, MT, alongside one of the strongest live plant selections in the region.
The planted-tank gear — aquascaping wood, live plants, and the supplies to build high-tech setups — is the kind of inventory locals usually expect only from big-city stores. On the saltwater side, the team stocks corals and marine livestock with the same care, which is why aquarists searching for corals and saltwater fish near Billings keep finding their way here. Curiosity-driven extras like isopods round out the mix.
What sets Treasure State apart is how they treat the animals. They quarantine fish before selling — a step most shops skip — and reviewers consistently report taking home vibrant, healthy stock. When something specific isn't on hand, the staff will track down and special-order hard-to-find species.
Free water testing and patient, hands-on guidance have helped first-timers cycle and stock their very first tanks with confidence. The display tanks are worth the visit on their own; customers have built stunning 60-gallon setups with the store's guidance. Beyond livestock you'll find a wide array of supplies, tools, and tank decor, plus fish food and dry goods at fair, competitive prices.
From a nervous beginner's first betta to a 20-year veteran calling this the most knowledgeable staff they've ever met, Treasure State is where Billings goes for healthy fish, lush plants, and aquascaping done right.
