Thoughts on this? It popped up literally overnight. At first, I was thinking it scraped itself but perhaps it could be a fungus. I did a 50% water change and the fish is eating (seems not bothered). I am in the process of setting up a hospital tank and was thinking along the lines of api pimafix and salt (half dosage) as these fish are more sensitive.
