Another question for you guys. I have been battling with what substrate to use between cypress mulch and unprinted newspaper. I really love the natural look (as it is going to be display tank), but Im worried about the possibility of mites. Even though I do love the look, I care more about the well being of my baby then the looks. Are mites a really common problem with mulch or is there a way I can make sure I never have them in there or should I just go with unprinted news paper. Thanks in advance!!
