My fish love this food, They, as soon as it fell in the tank went to town. It clearly states the instructions on the side of the small container which is nice, there was odd thing that i saw tho…..”return to store for Refill” was written on the side of the tube?. I have never taken a free sample any where for a “top off” let alone find a store that i can return it to for re-filling, i will have to see if there is one around close to see if this works for this item. The brochure says its from CA, thats a long way from me!. All in all a nice small sample to at least see if your fish like it!. Thanx
