Noticed an injury on this guy a couple weeks ago and it has probably been infected as if it wasn’t it would have already healed by now. It hasn’t gotta much better or worse so I’ve been trying to treat it with clean water.

Then earlier today I noticed this one giant danio in my group of 5 had a similiar infection in a similar place but I never noticed any sort of wound on him prior. He is now dead the same day I took this photo. He looked like he could’ve been saved earlier today though it happened pretty quickly so I’d like get this figured out before I lose any more fish. I suspect bacterial infection.
