I have a plastic five gallon Critter Keeper used for reptiles and I was wondering if it was O.K. to use it as a fish tank for the red cherry shrimp I'm going to get? It holds water fine, I checked that. It has a few scratches, though. Do you think the heat of the water will make the plastic melt into the water and make the fish/invertebrates have cancer? I don't know if it's possible, but I was just thinking how people say not to drink bottled water that was in your car for a few days because the plastic chemicals would melt into the water(or somethinglike that) and make it cause cancer.
