and cage setup that you are maintaining this anaconda within. Greens are very hardy and definitely not inbred at this point. Therefore it is rare to see one with an RI like this unless something is seriously lacking in the setup. Have you had this snake for long, or is it a recent acquisition? What are the cage temps, pool temps (if using), and humidity sources and levels if known? These can all contribute to the problem if they are out of acceptable ranges for this species.
