I always thought epistylis was the benign-by-default fungus that lives everywhere, in every tank and would feed opportunistically on necrotizing tissue on fish if it happens to be. I saw large, dense, semi-clear bristles of fungus grow on dead skin of many of our injured fish. The skin would fall off and new skin would start growing soon. Epistylis is said to be known to attack healthy tissues too but I've never come along such a case IME. It always consumed the dead tissue. It is also the "fungus" that grows on uneaten feed or a dead fish if left in the tank. I think. Because it looks the same.
I didn't know epistylis is so broad a word / definition. Thank you.
Also, I didn't quite know that ammonia burn can kill surface skin cells and that epistylis would seize on this and start consuming the dead skin cells resulting in the confusing ich / velvet - eresque look. Thank you.
Never have done any bacterial culturing to determine which antibiotic to use. Nor do I use a microscope, like you do.
You are so far ahead of my primitive knowledge and experience.
I don't know how you have determined the timing of what's going on with this sick RTC, how much time past between what, but I trust you have.
