How long can a fish survive without food?

  • I have an important business meeting that's going to take me at least 10 days before I get back to my house. Do you think that my fishes would survive till I get back?

  • I think it really depends on their diet, how often you feed beforehand, and what species specifically they are. I've left my fish after slightly overfeeding them for a week without any issues - however, if you are gone for that long it might be wise to buy those automatic feeders in order to keep them feed until it runs out (normally they can drop enough food for about a week or two).

  • If the fish are fed correctly and have a rich diet, I’d think they could make it about a week. I’d agree with buying an aromatic feeder and setting it to run every other day vs. every day to increase the length it will work.
