Hummm... does he have injuries to his mouth?
And a little hint: Get some frozen brine shrimp, melt the cube in a cup with some warm water. Then take a turkey baster and put it just in fromt of this face... it may entice him to eat for ya.
This is a pic of one of my males not too long ago. As you can tell from the pic, he got his butt kicked something but good. He died a few days later.
