I am planning on getting my first crested gecko soon. I will be putting him in a 20 gallon high aquarium, will this be sufficient? If not I see the cages in the pet store that are all screen, are those good? Here is my one main worry when it comes to non desert geckos (jungle?) I got a blue tokay from someone about 6 months ago, I didnt notice when I first picked it up, but looking closely at the cage, I noticed it was infested with very tiny white mite like bugs. Needless to say I cleaned his cage and replaced the substrate (which looked like it had never been replaced) and gave him to my cousin. It was the wetness that drew those bugs, the wetness and the fact that the substrate was never changed. It just turned me off to anything other than leo's, but Im willing to try again. Have any of you had any bad experiences with raising cresties? Any tips for a first timer?
