I've sold them but never kept one. Tank has very little coral mainly just what I couldn't get off when I sold everything else. Even though they are reef safe trigger I am not worried about that. Only inverts are a horse show crab, urchins, and some starfish. But how aggressive are these triggers. My fear is i have a small snowflake and some smaller clowns. Only want knowledge from someone that owns/owned a blue jaw not links to pages
