Yet another ingredient you want to avoid in your hermie foods...I just wanted to post this because it is found in many of the Hikari Cichlid formulas that people have been buying. Gertie has indicated that it interfers with calcium absorption and should not be fed in combination with fresh fruits and treats. You may want to keep this in mind when buying commercial foods. I would certainly not panic and start throwing all of your food out, but if you are significantly concerned, take it back to the store where it was purchased. I may get a few strange looks, but I have not had anyone refuse to at least give me store credit.
