Best thing to do is look at the ingredients, if you are still unsure then post them on here.Sorry for your loss ccole, I Love fish also do a range of pleco food pellets, is that safe to use?
I am in no way defending P@H but this issue is a medication problem and other companies also use the same ingredients. The thread has turned from a medication problem to a company bashing one. If P@H did pay you compensation then that's far more than you would of got from most stores and tbh I never even seen anyone manage to get compensation for a medication that has wiped out their stock.
