Tank and Humidity Questions

I recently went to the ATL Repticon and fell in love with Crested Geckos. I've been doing some research, and have a couple of questions. Can an gecko live in a 10 gallon tall tank for the rest of their lives? What substrate is best to use? When it comes to humidity how often should you mist and what is the ideal humidity?

A 10 gallon is ok to use for a yearling but a full grown adult will need atleast a 12x12x18 or the larger exo terra verticle enclosure. A baby up to a year old will be fine in a extra large kritter keeper since baby crested geckos have a hard time finding food. If you want a cheaper cage for adult a high plastic storage bin with large holes covered in mesh would be good and cheaper then a glass tank.Also use paper towel until it is over 10 grams because babys tend to ingest bedding but coco husk or eco earth is the best for humidity. Mist twice a day if your house is drybor if not once is ok to keep himidity steady. Provide alot of plants and climbing branches and vines. And make sure you have repashys crested gecko diet and you can give treats of crickets which are gutloaded and dusted. Goodluck!

Thank you so much!!!

Thank you so much!!!

Also if I provide 2 bowls of food, would it be ok to put a baby gecko in a 12x12x18?

Adult cresties need a 20 gallon tank at least. I use paper towels for my cresties' substrate and it seems to work fine, especially if you are going to breed them.
