I'm new to the saltwater fish hobby and I want to add anew anemone. I have a 49 gal bow front tank with 2 clowns 1 firefish 2 Peppermint shrimp 1 cleaner and 3 nassarius snails. It's a new tank only about a month so I know I need to wait at least 6months to add an anemone. But when I get around to it I need to buy better lights. When I add the anemone will it kill my shrimp and firefish? Also can I have only 1 anemone and not add any other coral or would the lights be too strong and cause a huge algae bloom?
