I had to go on a trip to new zealand recently and entrusted a friend
of mine (who already had a little experience with goldfish) to look
after them. I gave a huge goldfish tutorial, like what times to clean
the tank,testing the water quality,syphoning under gravel to suck out
hidden food and poops, symptoms of diseases,how much to feed,and what
brand of goldfish food to buy,and when to put in new filter wool are
some of the things I taught her. She seemed to understand it clearly.

Really depends on the duration of the trip. Even out to a couple of
weeks benine neglect is often a better policy than trying to train a
non-fish person to be a fish-person...
