Rainbow crawlers make great pets. They are clean and can roam freely on your walls. An adult is approximately 18 inches long from the tip of it's nose to the tip of it's tail. They eat a small amount of fruit each day. Many rainbow crawler owners grow mini-fruit trees in their homes where their pet can feed as needed. A happy and healthy rainbow crawler will lay a clutch of 25 to 30 multi-colored eggs (known as Skittles) every morning. The Skittles candy company owns the three largest rainbow crawler farms in the world. By stamping a small white "s" on rainbow crawler eggs, the Skittles company has found a successful marketing technique for these delicious little treats. M&Ms did a similar thing over fifty years ago with fudji monster droppings.
