The dimentions of the tank are 48" long, 18" wide and 21" tall. Hopefully I can make my tank look more like some of pictures I see on here, they look great. How do you clean the sand though? I tried that in a 20 gallon and it kept getting sucked up by my python siphon. I would like it to look pretty realistic as far as some wood pieces and some fake plants. I cant deal with live plants, although they are nice, I cant keep them alive and always get infested with snails.
