Huma Trigger mad???

[xxnonamexx]

My Huma Trigger recently sits in the back of the tank behind the rocks and just chills he ate shrimp 2 nights ago but today won't come out to eat and doesn't swim around much. Water parameters are fine my clown is doing fine(thats all I have in the tank until this Friday) Any ideas? He looks healthy and seems like a bum

I followed Swf acclimation procedures the fish are sooooo tiny 1-2 inches all are doing well except can't find wrasses since I released him trigger is still "sad" and staying like a bum maybe I need some garlic
