Feeding schedule change....
Just picked up a new substrate to try out. It's a bag of super crushed walnut shells designed for reptiles. The grains are a little bigger than sand. The humidity holds the same, which was my main concern, and is supposed to be harmless in case of accidental ingestion. Not a concern to me as I feed in a feed box with astroturf as substrate.
Anybody use this stuff? Cleanup is nice, because you can just scoop out waste kitty litter style. Also added some fake vines and covered the back wall and one side wall of the tank with aquarium background paper. Xaero has a whole new attitude! He grooves on the walnut, and feels MUCH more relaxed with some leafy cover.
