I did not shoot down the internet. I shot down caresheets. Caresheets are *typically* written by someone who beleives they have experience, but kept the animal alive for a month. Caresheets should only be written by keepers who routinely BREED their animals have have over 5 years of experience. Usually its just 'Petco Joe' who writes them.
If you need a place to research reptiles, kingsnake.com is a great resource. Also pangeareptile.com has a gecko forum, and many members keep pictus.
Research does not have to be just caresheets, my friend. The best form of learning husbandry besides keeping itself is reading day-to-day accounts of keepers. Thats the beauty of a forum. You can also try books, but be careful. Most are outdated and dangerously inaccurate. If I had a specific book to suggest to you, I would. Just my only suggestion was to change your subtrate and fatten him up is all, dont take it in offense. I like to be brutally honest, and some people think it 'disrespects' their husbandry. I always have the animals best interests in mind, not the keeper. Good luck with your gecko!
