Your snakes not gonna get hurt falling from that tree or from the top of the tank!!! Whats the height like 14inchs? I have that same exact tree along with 2 other kinds and all my snakes use them. Do they fall??? Yeah but its nothing thats gonna hurt them. OP I would can the half log and pick up 2 small black zilla hides and youll be good. KEEP THE TREE IN!!
