I have posted in the emergency section too.
This angel came to me last week, I first suspected heater burn as the previous owner had no idea how it happened. However a week on and he is getting worse. I have been doing 40% daily waterchange and treating with myxazin now for 6 days.
Pic when he arrived (the blue tinge is the reflection of my t-shirt)
But now the holes are much larger
Any ideas what the heck this is???
