Well I have seen this post here for a while, but I do not work with Aspera so I figured I would let someone else answer it. But since that doesn't seem to be happening, here is my 2 cents.

First off what kind of temps are you running? And do you have a large water bowl in the enclosure? Most of my candoia only deficate in the water bowl.

I would say as long as the snake is eating readily that you probably don't have anything to worry about.

Here are a couple links to candoia sites....

Good luck and keep us posted....
