I had my father watch my fish for 2 weeks, and instructed him to feed them every other day. I wrote every detail out, how much, where to place the food, etc...I have 3 38 gal tanks. To my surprise, he actually did agood job. All my fish survived, and stayed healthy. Just goes to show you, once in a great while you can find somebody worthy of fish sitting....im pretty sure I just got lucky
