As I was doing some of my usual cage maintenance yesterday, I began to think about what type of bugs I should add to my CRB's viv, to make cleaning a bit easier. As I was changing and scrubbing the water bowl, I began to think about how I could set up a bio-active water bowl. So I looked it up, but all I could find was info for bio-active substrate. Has anyone else done this, or think it could be a good idea? And if so, how do you think one would go about setting something like that up? Just wanna say thanks in advance for any tips anyone might have.
