Based on the pictures, it doesn't look like he has hexamita. I know you said he was eating fine, but does his poop look normal?
All cichlids have sensory pores in the head area, as part of the lateral line system, some more than others
Take the Stomatepia pindu below, some of the white areas (emphasized by the cameras flash) are sensory pores that help it detect prey hiding in mud and leaf litter.
That said, as any cichlid grows, your water change schedule should be increased in volume, and frequency, to reduce stress, and stress from poor water quality is a major cause in fish getting Hole in the Head.
If when your cichlid was 1" and got a 10% water change per week, at 5 ", they may need a weekly 50% water change to stay healthy, and dilute the by-products of metabolism and fish urine.

If it was hexamita, his poop would likely be white and stringy. If you are really worried, you could take a poop sample and look at it under a microscope at 200–400× magnification.
I'll keep ya posted. I havent noticed any white stringy stool, but I'll definitely keep an eye out.. thanksBased on the pictures, it doesn't look like he has hexamita. I know you said he was eating fine, but does his poop look normal?
