It went sour even with Andrew's mix. I'm think their too small to take the dose.

I've started force feeding and with good results. All are now eating with out my help. Going to keep feed them 3rd and 5th day.

What I'm concerned about will it return seems I'm not treating the water. In a bit of a bother here as I don't want some super bug. I have read that if the water is kept clean and fish are happy and health they will keep it at bay.
