I do not feed my fish when I go away. There are FAR too many things that can go wrong, and since I over feed they could stand to lose a little girth
It takes a LONG time for a fish to starve to death. After reading posts about how fish will die without food for a week or two, I decided to do an experiment. I placed a fish in a barren 10 gallon. I cut the experiment short after 3 months. I know I know, I'm terrible and cruel....but I think spreading misinformation is worse, and it was done in the pursuit of knowledge.
I don't see anything wrong with not feeding the fish on weekends. That's pretty much my standard operating procedure - my tanks frequently go 2-3 days without being fed. in fact, i don't think they have been fed since friday night. Tomorrow I'm going away for a few days so i should probably feed them. There are things in the tank for the fish to snack on while you are away - the aquarium is far from devoid of food.
