I put him in it when I thought he had chytrid to use as a quarentine hospital tank. Since the vet said there were no signs of chytrid I decided to just place soil in there and leave him for now. I can see where the hight is wasted. I figured the hight would help keep there dylight blue light I use from being so close to him. I guess I can always switch back later if needs be since I plan on keeping the 10 gallon.
