The original Albino cal king male, w/c in Balboa park, lived in captivity for 35 years. It was housed at the S.S. zoo And at least three private keepers for that period. I had him and bred him for 22 years I believe.
So your king is good to and still a youngster.
I had a friend, Bill Wooden, who had a Yuma king for something like 45 years if I remember correctly. His was kept cool and only fed a few times a year. The albino was fed and bred like mad.
