Are electrical outlets and a water source nearby?
Electric outlets need to be close enough that you can plug in aquarium equipment without having to use extension cords. A distance of no further than 3 ft away is best. The extra cords are not only a tripping hazard but a tangle of equipment cords is a serious electrical hazard. If possible, locate your aquarium close to your water supply to make crucial water changes and other aquarium maintenance easier for you.
