www.iansvivarium.com will show you pictures of morphs as hatchlings and adults, and their colors DO change from hatchling to adulthood. Check out that site to see! Here is a link to the Munson Plan for feeding. Use it as more of a guide as not all snakes will conform to it exactly. A basic rule of thumb is no more than 1 1/2 times the widest part of the body. If the prey item doesn't make a feeding lump, it may be time to bump up to the next size prey item. Alternatively, if the feeding lump is very large and present for more than 4 days, the prey item was too large and you should definitely bump down.
