I was wondering if a Rubbermaid container would be suitable for a tank? I have about 40 fry that are 1/2-1 inch that are in two ten gallon tanks and I have 6 fish that are about release their fry. I saw a huge 50 gal rubbermaid container and wanted to know if I could set it up with a filter heater and let the fry grow a little bigger in there before I sold them to my LFS. Would the plastic hurt the fish or do you see any other problems in doing this.
