Hello, I just found a centipede in my substrate bin. I don't know how it got there but I caught it and put it in a small container. I put a little bit of damp coco-fibre in the container and a small spider i found in the basement. I want to keep this centipede and i'm wondering what I should know. It ate the spider that was it with it right away, the centipede is about 1 1/2" long which is the biggest I have seen in Alberta.
