Well today 25 April 2012 is cold and wet (12 degrees and its been raining heavily). For anyone who doubts that Diamonds don't like it cold here's some convincing evidence. At 12.30pm all three of mine were out and active (slow mind you) and this is typical of my snakes throughout winter in Melbourne. And it's not an artifact of captivity. A friend of mine found one out and about at Ben Boyd N.P. in southern NSW in August. Again it was around 12 degrees and drizzling. In APPROPRIATE enclosures this species does need heating outdoors in Melbourne. These animals are outdoor 5 year captives. This pic taken today at around 12.30.
The longest lived captive Diamond I'm aware of was about 16 years. It was on display in the Zoology Department at Monash University and died sometime in the 1980's. It was in a large glass fronted case with a basking branch, a mesh top and a large waterbowl. He ate a rat about every month, less over winter. Basking temperature in the 30's from 0900-1700 and "Monty" shuttled from under the light to curled up in the corner. At night the temperature dropped down to whatever the building temperature reached (I'd guess 10-15 degrees by early morning). He was obtained as a wild caught "teenager" and was a celebrity to a couple of decades of students there. He was a true Diamond, not an intergrade and was black with scattered cream spots - I don't know where he was caught. Replicate that and you probably have a winning husbandry combination (you might have to get a bunch of students to press their noses against the glass daily to fully replicate the set-up. :lol:
