Thank you . About humidity this seems to be an issue... usual humidity is 48% there... (let's say 46-50). However por last few days every evening when I got back from work is humidity 40% . So I have followed advice #21.

21. How can I increase and maintain higher humidity?

One simple way is to move the water bowl over the heating pad. Another simple method is to use a spray bottle, but monitor the bedding so that it does not mold or become too wet and cause belly rot. If possible try avoiding heat lamps and ceramic heaters, as these suck the moisture from the air. Covering a screen top with plastic wrap, Plexiglas, or clear contact paper also works well to trap humidity. (Do allow some open space for air circulation if you choose to cover a screen top.)
...but still it's not enough... max I can got is 50%... so I have bought small waterfall from Exo-Terra and running it during a day... I hope that will help a bit. If not I just do not know what to do next
