The feeder, when placed in your aquarium, will thaw and slowly release small particles of food.
One shell feeds 15 medium-sized fish in a 50 to 60 liter aquarium for 2 to 4 days, depending on pH and water temperature.
For best results, the water temperature should be 22°C or higher and the pH should be in the range of 6.8 to 7.2.
In addition to feeding your fish, the ingredients will help neutralize and purify your aquarium water.
