The size of your commercial minnow tank will depend on the number of minnows you plan to raise. A good starting point is a 100-gallon tank, but you can scale up as your business grows.

Key Considerations:

  • Tank Material: Fiberglass or concrete tanks are the most common choices for commercial minnow tanks. They are durable and easy to clean.
  • Filtration: A robust filtration system is essential for maintaining healthy water quality. Consider using a combination of mechanical, biological, and chemical filtration.
  • Aeration: Minnows need plenty of oxygen to survive. Use an air pump and diffuser to provide adequate aeration.
  • Water Temperature: Maintain a consistent water temperature between 65-75 degrees Fahrenheit.
  • Lighting: Provide adequate lighting for your minnows. A combination of natural and artificial light is ideal.

Feeding Your Minnows

Minnows are omnivorous and will eat a variety of foods. A good diet should include:

  • Commercial minnow food: This is a convenient and balanced option.
  • Live food: This includes things like brine shrimp, mosquito larvae, and daphnia.
  • Plant matter: Minnows will also eat algae and other plant matter.

Maintaining Water Quality

Water quality is crucial for the health of your minnows. Regularly test the water for:

  • pH: Maintain a pH level between 6.5-7.5.
  • Ammonia: Keep ammonia levels below 0.25 ppm.
  • Nitrates: Keep nitrate levels below 20 ppm.
  • Dissolved oxygen: Ensure dissolved oxygen levels are above 5 ppm.

Harvesting Your Minnows

Once your minnows reach a marketable size, you can harvest them. Use a net to gently remove the minnows from the tank.

Marketing and Selling

There are a few different ways to sell your minnows:

  • Retail stores: Sell your minnows to local bait shops and sporting goods stores.
  • Direct sales: Sell your minnows directly to anglers.
  • Online marketplaces: List your minnows for sale on online marketplaces like eBay and Craigslist.


Starting a commercial minnow tank business can be a rewarding and profitable venture. By following these tips, you can set yourself up for success. Remember to always prioritize the health and well-being of your minnows. Good luck!
