I got a really nice tank from the thrift store. It's a Zilla 20 gallon. It was missing the top, but I contacted Rob Moneyhan (someone from Zilla) about a replacement and they shipped one to me free of charge. I haven't received it yet, but he had to order it for me, and should be here in a couple weeks. Try looking for them at second hand stores. We got the 20 gallon for 5 dollars. Very much worth it.
