When I asked a friend to petsit for my rats and fish, I wrote to only feed Odysseus specified amount, no more, even if he looked hungry, and not to feed my fish upstairs at all, because it would do more harm than good by fouling the water. She read my instructions, thank goodness. :)
I don't understand why petsitters don't understand that your instructions regarding your animals are correct. Don't they think you might actually know what is best for them?
i think it has to do with how they were brought up and the fact the fish will eat themselves silly (cant forget the hunger dance). my parents neighbor had a betta in a tiny vase, she fed a pinch of FD BW. he never ate it all BC he was in unheated water. humans assume too easily that what they can eat is a similar amount that other animals can. i told her the size of a betta's stomach but it didnt click either way. i can easily see the uninformed think they're still hungry BC they still beg for food any time you walk past the fish.
