I have two ten gallon tanks for $10 each. And a 20 gallon for $20. They have cracks in them but they can be easily fixed with some super glue. I have patched one of them but I’m not sure if it will hold water yet. They need to be cleaned but other than some normal wear and tear they’re in good condition. Ideal for most fish. Can take all of them for $30. There is also two small water dishes and a small plastic log hide if you want those
