Ok, so I finally got my lr, I've been waiting for like, 6 days, which feels like an eternity,but it came today. As soon as I locate my digital camera, I'll have pics. I will tell you before hand, though, I am NO artist! I just tried to make it stable and not too close to the sides. I will be getting a 29 gallon within the next few months and will have lots more placement options. One rock came with this awsome little hole in it. I tried to make some tunnels and caves. I'm really happy to get the process going. I'll check params later tonight!
