Diet Gerbil food is available at many pet stores, but gerbils can be given sunflower seeds, nuts, alfalfa pellets and fresh vegetables as well. Be sure to clean up any leftover fresh food before it spoils. It is best way to provide water is by using a bottle with a drinking tube . Behavior Gerbils' teeth grow continuously, just like those of all other rodents. So, it is important that they be given a sterilized bone or twig that has not been treated with pesticides or any other chemicals to gnaw.
Gerbils are social animals, so it's best to get at least two.
However, since gerbils are prolific breeders, keeping males and females together is not recommended unless you are going to breed them, in which case, the best way to introduce gerbils is before they have become sexually active. To introduce gerbils, set up a clean tank with a mesh divider down the middle, and make sure the divider is very secure. In one side place the female and leave her in that section for an hour or so to give her time to scent the area. Remove the female, then place the male gerbil in the other side of the tank. Again, leave him for an hour or so to let him scent his area.
