I Think They've Started To Sing

I checked the tank and I started to see some condensation on the glass around the edges and it's started to feel warmer inside the tank. I've been pouring a vase of water in about every other day. The level of the layers has gone down about half an inch. Although right by the sweet potato it measured 15 inches. It was 17...I wonder if we measured wrong or what, because it doesn't look that much different.

We've seen a couple of the worms tunneling against the glass. They are starting to look healthier, like redder and denser. You can see the tracks of where they've gone. One side of the tank is almost completely tracked. It's pretty hard to see the tracks. I tried to take some pictures, but they didn't really turn out. The tracks are very skinny and shallow, and it's dark in there.

We put in some more lettuce, coffee grounds, and some onion skins. But they haven't really shown any interest in that. I'm glad they're looking healthier. And they hope they eat the compost.
