is ick a bacteria or a fungus?

Hello; I believe ick is a parasite that burrows into the body of the fish. There may well be secondary bacterial or fungal infections due to the weakened state of an afflicted fish, but the parasite is the issue with ick.

Ich is a protozoan parasite. I.e. neither fungal or bacterial.
