| if it's just wednesday through sunday then i wouldn't feed them or i'd separate food into plastic bags for a family member or friend to feed them. a lot of times automatic feeders end up putting in way too much or way too little, but i dont have any experience with the specific one you mentioned. however, letting fish go without food for less than a week is perfectly fine. if you'd rather not do that, then see if you can get someone to feed them for you. but like i said, make sure you separate the specific amount of food you want them to add into bags, even the most well-intentioned people can significantly overfeed your fish if they don't know anything about them |
