I personally would try to find a 55g, you can use the water from your display tank and replace the used water with new and consider it a water change for your display tank.
You can put a sponge from your display tank into the new QT to give you a biological filter, just don't put it back into the main tank without sterilizing it first. And remember no rock or sand in the QT, use pieces of PVC
for hiding structure.
