Honey fill it up on one side with substrate like a big hill, that will cut down the space and you can half bury her hide in it so it looks like she burrowed into the hill. save getting a new enclosure.Ok thx I wanted to go with the big enclosure bucuse it's my only t so I don't need room and it was only 2 dollars more that the 5 gallon one this is a 10 so why not get it
