  2. Clean the tank. Rinse the tank with water to remove any dust or debris. Do not use soap or detergent, as this can be harmful to fish.
  3. Add the substrate. Add a 2-3 inch layer of substrate to the bottom of the tank.
  4. Add the decorations. Rinse the decorations thoroughly before adding them to the tank. Be careful not to overcrowd the tank with decorations, as guppies need plenty of swimming space.
  5. Fill the tank with water. Use dechlorinated water to fill the tank. You can use a water conditioner to remove chlorine and other harmful chemicals from the water.
  6. Install the filter, heater, and air pump. Follow the manufacturer’s instructions to install the equipment.
  7. Cycle the tank. This involves establishing a colony of beneficial bacteria in the tank. The bacteria will help to break down fish waste and other toxins – The Ultimate Beginners Guide On How To Cycle Your Tank: Tips and Tricks For a Healthy Aquatic EcoSystem

  9. Add the guppies. Start by adding a few guppies to the tank and monitor them closely for any signs of stress. If the guppies seem to be doing well, you can add more fish to the tank gradually.
