Yes, pet fish are low-maintenance pets. Compared to dogs and cats, a freshwater fish is a walk in the park (not literally, they don’t like that). However, fish are still animals that require care and attention. Quick weekends away and lengthy vacations alike call for reinforcements when it comes to leaving a fish home alone. Food is the biggest factor when determining how long you can leave a fish home alone. Depending on the type of fish, how many fish you own and the size of the tank, you can leave your pet fish alone for two to seven days.
