All things in moderation, including copper.

Interesting fact about shrimp though, they ABSOLUTELY need copper. Their blood uses it to bind oxygen like our blood uses iron. In small amounts, they're fine. In larger amounts, it becomes toxic. If you dose according to the directions on the package, your shrimps will be fine.
