well what size is your tank? and what other fish where you interested in would be my first question then I would gladly give you my recommendation's. the neon dottyback will need to be watched as well as trigger as they may nip fins however I would add the lion when lights are out and maybe move a few rocks to make it appear as a different setting when the lights turn on in the morning hours. then monitor there interactions.
