I finally have my terrarium together and have put my baby into it, however, I did the dumbest thing. I think that the terrarium might be too big. The tank is a R-Zilla Acrylic tank (18"L x 12"W x 20"H) that I bought from Matthew Parks at one of the reptile shows. My crested is approx nose to end of tail, a tad bit shorter than my index finger. IS THIS TOO BIG???? If so, I am going to switch my larger cresteds (which are in a 10 gal until the next reptile show, when I buy 3 more tanks!) into the R-Zilla and put my baby into the 10 gal. LET ME KNOW, Please!
