I went to my LFS and saw they had a small snowflake eel. I currently have 2 smaller clowns and one large one that’s hosting an anemone, 2 blue tangs one is 3 years old and another is 2 inches, diamond goby, blenny, yellow tang, sailfin tang, damsel, and a pistol shrimp along with 2 anemones and some corals. Would this be a good idea to get one? Will it kill my fish?
