Obviously none of you have run out of fish food but I did once! It's an hour drive to the nearest pet store and I'm not about to run out to get one item that cost under two dollars and spend over $2.50 for gas to get it! So while I made up a list of needed items to purchase over the next week - to justify a trip to the pet store, I soaked my dry dog food in water until soft and mushed it up and gave little portions at a time to make sure that it got eaten and the guppies loved it! It was great as an emergency fish food. Since then I soak their crunchy Tetra-min granules until mushy and use some bunt-end treezers to feed the mushy fish food a little at a time. I don't ever think I'll give them the crunchy stuff dry again!
