See the difference a dedicated staff makes

We opened Treasure State Aquariums with one goal in mind: To bring a wide variety of healthy aquatic livestock to the Montana area. Our staff has years of experience in the pet industry, and just a year and a half after we opened our doors, we were able to move to a larger location in Billings, MT.

Treasure State Aquariums can help you grow an active freshwater or saltwater tank. Visit us today to speak to an educated member of our team about your dream aquarium.

We stock healthy marine plants and animals

Adding a sick fish or invertebrate to your tank can cause a catastrophic chain reaction. Because we’re passionate about marine life, we take the extra steps necessary to keep our livestock healthy.

Long before our livestock gets to the sales floor, it’s:

  • Quarantined
  • Inspected for ailments
  • Treated for disease
