Help Me Please!

One of my cardinals head has turned white and it looks like its about to die. What is wrong with him? I'm worried it's going to spread, I'm considering culling him to save the others. RIP!

I know exactly what you're talking about.... have seen it more than once in my tanks & have been unable to save them.... Anyone with advice would be helping me as well.... it not a fungus that grows on top.... its more into the head like it's causing a fibrosis of some kind.

Yep I have flushed him now, poor thing. Dead within 24 hours. Fast killer.

I think I suffer form OCD as I can't stand having odd fish in the tank
