Marine Invertebrates for Beginners

These are marine invertebrates proven to be hardy, undemanding, and well-suited for the beginning hobbyist. Invertebrates are sensitive to copper-based medications and should not be housed in aquariums treated with cooper sulfate. Sea Stars and Fan Worms do best in well-established aquariums. The diet of Fan Worms should be supplemented with foods designed for filter-feeding invertebrates.
