I have a Crestie that is 21 grams, has been eating very well and overall was in great health.

I had him in the 12x18x18 exo terra and it seemed as though it was kind of small. So I got him the 20 gallon long and turned it upright. This was a week ago roughly. He hasn't eaten much at all, he has been spending almost all of his time at the top wedged between the plants hiding. Well I checked on him tonight and picked him up. His skin is really loose on his body, almost like he is dehydrated. He is also really pale, Not the "not fired up" pale like sick pale. I sprayed him and he was just sucking down the water.

So my question is he is Obviously VERY stressed and not taking to his bigger environment. Should I go ahead and move him back to the smaller one? Or will this stress him more?

I do have the tank still all setup and hadn't cleaned it out yet due to the fact that I had just cleaned it. So it has all his old "stuff" in it.

Oh and Btw Temps are between 74 and 79 and then a very slight nighttime drop. I mist him at night and bring the humidity upto about 85% and then just let it drop to about 50% and mist again. Papertowel substrate. Fed CGD and Crickets. Lost of Foliage and branches and hiding spots.

Thanks,
Kristy
