golden/albino clownknives mortality?

[kido]

guys anyone keeping golden/albino clownknives? i'm planning to buy one and i was wondering how long they live? i'm assuming they grow as big as the regular ones (24") but i haven't really seen any big ones at lfs' or pics at the forums posted which leads me to question their mortality rates?

if anyone's got some big ones kindly post some pics.. thanks

oh and do they keep their cirlcles marks when they grow

I have a young one, but he has been just as hearty as a common clown knife.
