I've noticed that, it's pretty funny just seeing a nose pop out from under the fiber. However, he/she is completely buried under the substrate at the moment. I added a bit more than usual when I did a change a couple hours ago, perhaps he/she is taking opportunity of that. I'd say there about 3 inches worth, last time there was only 2.

On a completely different note, how do you go about cleaning your frog's terrarium BG and GrifTheGreat? I've only done a change twice (only have own him/her for a little over two months), and this is how I did it: I let him/her soak in a tupperware container filled with shallow water, dumped out the substrate, hosed off the set up with hot water in my shower, dried it off real well, filled it back up with substrate, and put my little guy/girl back in!

Is that a good method or is there something else you two would suggest?
