Using snails to test for copper contamination is a used fish tank?
I found a used 20 gallon tank. The seals are white colored and watertight. I wanted to set it up as a dedicated shrimp tank, but was considering if it may have copper contamination from medicine. I have no idea if has of course.
After washing it out well, I was thinking about filling it up and throwing some snails in it, and see how they do.
Would that be a good way to gauge if the tank was safe for shrimp?
