I have had this leather since the middle of Dec of 2008. Its has gotten HUGE!!! Well within the last couple of weeks it has been loosing some branches on the top. I am assuming this is a natural process. We now have 10 new leathers in our tank. I dont know what we are going to do with them all. There is more that is going to fall off soon. What do you guys do when this happens to your leather? How often will this happen?? I have called my LFS and they really dont need any right now cause there business is super slow. We are ok for now, but when this happens again, and the new ones start doing this, we are going to be OVER RUN with these leathers!! Input greatly appriciated!!
