How can my fish live in an aquarium without food for 11 days?
I will be having a vacation out of the country for 11 days, and no one can feed my fish for me. Most fish are perfectly ok without feeding for about a week. If you really can’t get someone to feed them for you (with specific instructions & pre-prepared packets of food), you may want to invest in an automatic food feeder if you regularly go on holiday or out of town. Don’t buy those holiday blocks of food as they can dissolve faster than expected & foul up the tank.
