Depressed Niger Triggerfish

[dyno]

I don’t know if fish get bored or depressed. I guess no one does. My beautiful Niger trigger sits around and hides all day. He used to be a clown in the tank and was active all day. No signs of disease and no one is harassing him. I do have a huger Picasso in with him and am wondering if that is why he is acting this way?

What should I do? I can look for a new home for him if needed.

How big is the trigger and how large is your tank?

He’s big, 7-8 inches in a 120

You might want to set up a remote camera system to find out what's really going on with your tank when you're not around.

Is it possible he's just reaching the size limit for your tank? @davidcalgary29 has a great suggestion with the spycam.
