Remember that a quarantine tank doesn't necessarily have to be an aquarium. You can use a rubbermaid tub or anything else that will hold water if you don't have the cash or space to set up another aqarium. Of course, the advantage in using an aquarium is that you can observe the fish a lot easier, but anything that will hold water and is fish safe should do in an emergency.
