I never observed any permanent damage caused by the leather rubbing up against the cap. I just didn't like the way it looked and I felt that growth was being restricted. The leather was also starting to shade my frogspawn. The frogspawn was sending out sweeper tentacles that on occasion reached the leather. This was another indicator that it was time to move it. It's now on the sandbed under my green slimer and next to my colt. I'm not sure if this is an ideal location but it is the best location I have for it right now.
The leather had grown so that it was adhering slightly to a second rock. I needed to perform some delicate surgery to cut some flesh from the second rock. I'll be curious to see if a new leather develops from hat rock.
