In an effort to encourage social distancing during the current health concerns with Covid-19, TSAQ will be closed temporarily.

If you are low on essential dry goods (food, water conditioner, medication, etc.) please message us. We will set up a time for you to pick up those items. We are spacing pick up times so that there's only one customer at the shop at a time. We can also accept payment over the phone to make it easier and quicker for everyone. We will not be allowing people to buy in bulk so that there will be enough available for everyone's pet. We will be getting a new shipment of food in this week.

This does not apply to livestock, or plants. We will not be allowing people to browse the store, just pick up items that have already arranged with us for pick up.

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 Montana. 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 begin or expand your freshwater or saltwater aquarium. Visit us today to speak to an educated member of our team.

We stock healthy aquatic plants and animals

We understand the potential negative reactions that come from introducing disease or parasitic organisms to a thriving aquarium. We're serious about aquariums, so we take the extra steps necessary to ensure our customers receive the healthiest animals or plants possible.

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

  • Conditioned
  • Inspected for Injuries and Ailments
  • Prophylactically Treated for Disease and Parasites

  • Treasure State Aquariums
