Its 18x18x36 and she is currently only 55 grams. I have her in a sterilite shoebox setup right now. I am trying to decide if its worth moving my crested geckos out of the exo terra and converting the 29 into a vertical for them.. If she will stay comfortably in the exoterra for a few years I will go ahead and start planning to move her over..Thanks so much for any advice.
