No problem. One thing I had to consider was if it was going to be beneficial. I was worried I would be taking up too much land that would become avoided and not used. BUT, beyond the aesthetics, the creek provides the obvious source of water of varying depths and movements. Sometimes the tortoises like to lay in the faster moving water, and others they will take a dip into the deeper end of the pond. Having it cut the habitat in half forces them to become in contact with water more frequently, which helps to stimulate natural soaking, at least I believe.. If it were located in one corner of the enclosure, the water would be less accessible.I love it! Thanks for the tip -- a dry creek would definitely be the way I would go if I ever put one in.
A more general benefit would be acting as a sight barrier. I have started to build up the land on both sides to create more of a creek appearance. It may not be noticeable, but if one were to get close to the ground, it becomes clear that the tortoises can not see the other side of the pen due to the landscaping provided by the creek. I'm sure the same could be obtained by simply creating a hill, but its more interesting for both humans and tortoises.It gives them privacy from others, and may make the enclosure "appear" larger. I often see them traveling up and down stream like a highway, always inspecting, searching for new things like food items.
In general, with and without water, it seems to stimulate different behaviors that may resemble those that would be exhibited in the wild.
