Geckos come in a variety of beautiful patterns/colors depending on the species. However, as always, know what you are getting and what will be needed to provide a good home for a gecko. The requirements and difficulty of care will vary with different species, as will temperament.
Never grab a gecko by the tail, for they will often drop their tails (a natural defense against predators). If this should happen, however, do not panic. It will grow back, although it may have a different shape and/or color. The gecko should be well fed (and ideally separated from their cage mates) until the tail has regrown.
