Just confirming this is hole in the head and not a deformity

[FishyTJ]

I went away for 5 days and set my automatic feeder to low to ensure minimize the chance of over feeding but came back to two or three small "holes." His head increased in size since I left so just want to ensure its not the result of growth. Any input is appreciated.

how is he doing? the lesions resolving?

Much better, they are filling in after dosing of gen cure, furan2, and meth-something that is blue that I received from my LFS guy. However he now has some white mucus lining his gill on one side. Looking at the opposing gill I see nothing protruding the main gill outline but looking at the side with the mucus/white lining the gill protrudes the outline seen below

Glad he's doing better. When you try to treat HITH you are targeting an internal flagellate infection of Spironucleus. You probably didn't need to use all of those meds. People used to think it was hexamita back in the day, but in recent years spiro has emerged as the typical cause.
