What I do is keep a small container for what I use in a week and freeze the rest.+1 on the reviews. My fish litterally flip me off when I feed flakes or mysis now. Throw TDO in and they are jumping out of the tank to eat. Great food, last awhile, dont let the packaging fool you, the product is great, my only concern is my exp date is in like a month, was purchased less then a month ago from BRS, dose the food still hold quality even after exp date?
Thank you again for a great food
