What is CB or CH? I didn't really let the little guy get settled i guess, because i handled it the first few days i got it. I thought it might help it get used to me. To keep his tank humid i have been spraying water into the tank 2 times a day, and i have about half of the cover cealed off with plastic wrap. The other half is open. Im not sure the exact temp. or humidity, ill pick up one of those humidity measurers tomorrow.
