I'm not sure why but I'm sensing that you seem a little angry, perhaps even unhappy about something? Please explain your position honestly. In response to whether there is any new information for the experienced keeper? Obviously not, that article wasn't for directed towards the experienced keeper, nor was it titled 'Naultinus grayii, breakthrough husbandry for the experienced keeper and breeder'. It wasn't supposed to be comprehensive considering word count limitations and the fact that it was an article and not a book. Temperatures and lighting information is easily found either on climate tables or local weather websights which if you are interested in Tom, you can go to google and type in local climates for Whangarei or another NZ town close to where the specie originates to find records dating back decades and ending at the present date. Seasons, months, yearly high's and low's, precipitation figures, ambient humidity during all hours of the day, all months of the year, graphs, and much more helpful information is also included. I'm not studying the animals in their native New Zealand or writing a disertation on their husbandry or care so no unfortunately I do not have any new ground breaking care information for the official voice of naultinus, which has been very quiet at best. Perhaps I can suggest that you provide a detailed care sheet for specific naultinus species for this forum as your experience would likely benefit many. The books you mentioned are alright, but they are also very vague and they too leave the reader a lot of questions, and therefore I wouldn't define them as detailed sources of information by any means. I think this just brings us back to the fact that experience is indeed the best teacher. I have a hard time believing that keeping the jewels is as complex as you are implying, but since you have read the title of that article you must have noticed that it specified Naultinus Grayii, not the broad genus of Naultinus alone. Yea, and Tom in response to the positive and enlightening feedback I don't think you recognized the general point of the article, so if you need it translated into German for your better understanding I would be more than happy to do that for you. The dangers of moist and wet substrate in regards to fungal or bacterial problems is something that can apply to many reptile species and is almost an obvious statement. I wouldn't recommend a wet substrate for any reptile as moisture alone is a breeding ground for harmful micro organisms. Not that my naultinus even spend close to as much as .01% of their time near the substrate anyways it seems to be a topic that is known to effect naultinus, and can usually be remedied if caught early enough with decreasing humidity and increasing the temperatures a little in the enclosure. I hope I covered a little of what you are trying to prove, or the point that you are trying to make here.
