Tribal Blenny issue

[fuddruckers]

Had this blenny for a couple of months, I look earlier this week as its been less active than usual and its got this white sore on its face, it hasn't been eating , and now its much worse, it went from a black/ dark grey to a light grey/white and the sore has gotten massive, Im afraid its some kind of bacterial infection or parasite, so it got moved to a QT tank tonight.
TL;DR does anyone know what is afflicting my blenny and/or how to treat it? I feel really bad for the little guy and really don't want to lose it.

I would mix Metro, garlic extract, and frozen foods. I use Metro and Garlic most of the time myself anyway.

Good luck that is a nasty soar.

Dang.

Yep I'd say that's infected, perhaps a mechanical injury that went bad.

I'd get a broad spectrum antibiotic like Seachem Kanaplex and treat with that - in the water in QT (be sure to remove any carbon filtration).

If it's still eating, that's a good sign - you can spike the food with Kanaplex and Focus.

Hope he pulls through.
