You can also give them fresh vegetables. Gerbils typically groom themselves and therefore need no bathing. They will need some sand to roll in to absorb the excess oils from their fur. You can use regular clean play sand like what you would use in a child's sandbox. Put some sand in a container for your gerbil so he can roll around and shake the sand off.
Gerbils are very affectionate rodents and enjoy giving and receiving love.
You will need to spend time with your gerbil on a daily basis. Taming a young gerbil is easy if they were cared for in a non-abusive manner. Most well cared for gerbils will not bite. If you have a busy life and know that you aren't going to be able to spend every day with your gerbil, you can get a second gerbil so they can keep each other company. Gerbils that have been exposed to loving care generally bond with their owners over time.
