you can go to wall mart of what ever and buy a large plastic bins for breeding cheaper then tanks and they work better because they wont get distracted by seeing any thing outside of the tank. a heater or you could just heat that one room up to 80 degree with a few reptile heating lamps. plus plastic bins hold more heat and the the most important part is the nutrition I found. try a beef heart mix live baby brine shrimp and baby vinegar eels.
