Calcium Rich Foods For Aquatic Snails

By Susan Mast
 
This is a list of vegetables and fruits along with the amount of calcium in each 100 gram portion.
 
They are ranked in order from the ones that contain the most calcium to the ones that contain the least.
 
I would caution us all to remember when feeding these foods that the phosphorous contained in these foods can have an ill effect on your water quality and may cause an algae bloom if the levels of phosphorous become too high.
 
In my experience, it is best not to feed too much nor too often. I usually feed these types of foods the evening before a 25% water change. However, the choice, as always, is yours.
