Each tank/cage will need it's own water bottle. There are a number of styles and most come with a simple wire hanger to use with cages. If you are using an aquarium you will need to purchase a special bottle holder/shield. Be sure that the tip of the water bottle is well above the bedding. If the tip comes in contact with the bedding or other material it will drain out in a matter of hours. Even though gerbils are a desert animal they require clean, fresh water at all times.
Keep your aquarium out of the kitchen to prevent contact between dirty bedding and counters, utensils or food.

On the other hand, a large aquarium with its solid siding accommodates plenty of bedding for enthusiastic digging and tunneling and keeps the surrounding area tidy. It also lets in light; gerbils are diurnal animals, meaning active during the day, so need to be placed near a window (but not in direct sun) so they can experience cycles of day and night. 37 items - Find cheap aquarium bedding for free shipping, worldwide delivery.
