I kinda discard dryness, since the enclosure is always at 80+ humidity. What I now recently discovered is that the peat moss that I bought has something called "Perlite Agrolite". So maybe zovick's guess was right? English is not my native language, so I don't know if I correctly translated this. Does anyone know if this is harmful for my tortoise? Vendor said that the moss was not enhanced in any way, but seems that he lied to me. Also, I recently started noting lots of little bugs in the terrarium. Is this problematic? Or should I stop worrying?
