There's a really easy tank divider you can make even if you have next to no skills and it is really cheap.
You take a piece of plastic canvas (it comes in different colors and has holes punched in it, this will let water flow to both sides of the tank.) Cost: $1.50
Buy those report covers that are just a plastic spine, and a clear sheet of see-through plastic Cost: $2-3
Cut plastic canvas to fit down the middle of your tank.
Remove the clear sheets of plastic from the report covers and slide the stiff plastic spines down the sides and bottom of the plastic canvas.
The stiff plastic spines help keep the canvas standing up. Bury the bottom spine in your substrate, maybe lean a decoration against each side to keep it upright, and you are done.
