That looks awesome. I'm going to have AP just do a 10mm groove to be safe. Currently using eco earth as a substrate but not sure I love it. It's very bark-like and gets on the FT rat pup a bit when eating. I wonder if there is a cleaner substrate route. I know a lot just use paper but I'm not fond of the look since the display aspect is a goal for us. Any suggestions? Maybe something a little finer as a substrate? Snake is high piebald so I do like the darker susbstrate as a nice contrast for him. Not dead set on it to be dark, just a casual observation.
