Should I Have a Fish-Only Saltwater Aquarium?

If you expect to have to use copper-based medications, you should not include invertebrates in your saltwater aquarium. These medications can help get rid of many tank problems...but can kill many of your invertebrates, such as sea stars and snails.

If you do need to use copper-based medications, you can place your invertebrates into a holding tank while you treat your fish. Be sure to test for copper levels before you re-introduce your invertebrates and look for a copper removal treatment to help reduce copper levels. Never re-introduce your invertebrates until you test for copper content in your water.
