Just thought I'd share this experience.
Today I added a Niger Trigger to my 125g which is home to a large Yellow Tang and a large Sailfin. The Niger is medium in size. Once in the tank he went into an overhang (tunnel) that the YT uses to get to the back of the tank. The YT saw him and went after him like a terrorist! I hit the lights to calm everyone down. I left the lights off for an hour two and saw the Niger swimming with no apparent harm. I decided to turn the lights on again and see if everyone want something to eat. Feed some mysis shrimp soaked in Selcon and the trigger eat like a hog along with YT and everyone else.
<u>Lesson</u>: As the books recommend -- turn off the lights when adding a new member to an established tank.
