Using glass feeding dishes will allow you to control the removal of food.
Feeding dishes are made from glass, ensuring they sink and stay in place, also being aquarium safe and easy to clean.
Feeding Dishes are used to ensure that food doesn’t fall into the substrate where it can deteriorate and result in a fluctuation in water quality.
This is especially true with fine foods. Using a feeding dish allows the food to be contained, and the left over food can be easily removed.
