I've heard of many people using sterilite or Rubbermaid plastic containers to keep their fish in. I'm upgrading my goldfishes tank and I recently bought a 50 gallon clear container. Well, Amazon completely messed up my order and they don't even sell the product anymore. I got a refund, but I still need a tank. Apparently no one sells a clear 50 gallon container. I've looked everywhere. I've just emailed Sterilite, but my question is: does it have to be clear? I'm afraid if I get a colored one, the dyes will leak into the water and hurt my fish. However, colored ones are much easier to find. If I can't get a colored one, please share links to a clear 50 gallon if you can.
