I have a glow light tetra who was being cared for by a friend while I was on vacation, and when I came back he was covered in white spots. I assume it was ick. I immediately quarantined him and treated with Ick-X. A week later and he's pretty much cleared up. However, it appears that the lower half of his mouth is gone. This has happened before and I've never understood why. Did the Ick eat away at his mouth tissue? Will it grow back? He is having issues eating because it is difficult to draw in food with only a top lip, so I'm worried he will starve. I've searched the internet and found no results for a fish losing half of its mouth from a fungal infection.
