I'm setting up a 40 breeder planted and I just found a branch in my yard that fits perfectly. I'm not too concerned about bacteria or anything... and if it rots or something I can always throw it out and redecorate, but the problem is, if my plants start rooting to it, i can't really get rid of it. Will it be okay? I didn't strip the bark off of it or anything. What's going to happen in a few months?
