They don't like to be picked up by the tail. But gerbils actually loved being petted , so don't forget to pet them even if only for a minute a day. Gerbils are healthy animals and thrive in large aquaria with lots of hay, toilet rolls and bedding material . My gerbils usually have wooden houses too. They chew at their houses and hide their babies in them.
Gerbils can become extremely tame and are really perfect pets.
Gerbils do not smell and are extremely inexpensive to keep and feed. My gerbils can sit on my shoulder and never jumps away. The younger gerbils have a tendency to be active all the time and they seem to be almost unable to sit still for long. You only need two gerbils to fill a big aquarium, no more and no less. Gerbils are highly territorial, and need lots of space at the same time as they are very social animals, so pleace keep your gerbils in pairs.
