you can build a very simple stand out of 2x4s and wrap it in plywood , ive made one for a 50 gallon which was 36 x 18 , can easily fit 2 10gallons on top and a 20 on the bottom. i currently have the 50 gallon on top and a 29 on the bottom as a wet dry.
if you search youtube for uarujoey youlll find many diy videos, the stand design is one most DIY stands follow for the framing at least and then you can wrap it and put moulding as you see fit to match the room.
and just curious what kind of turtle your keeping in a 20 gallon , i keep turtles and theres none that i know of that will live its life in a 20 high , if its still a hatchling i would expect and upgrade pretty soon just so you know
