I guess a pet-sitter would be the best option for that ;0)

Im not into fish aquariums or whatever the proper english word for the small ones is. But i could make you automated fish feeder + other stuff if there is enough interest for this.

I am sure there would be alot of interest.

There are many automatic fish feeders available that run on batteries. I used one for my aquarium in the past, but I had issues with it dumping too much food in at once. They work with a rotating barrel-type dispenser.
