kole tang in bad shape, help

[jah-hoeva]

Any idea what this is? Never seen this before. I have formalin and cupermine on hand. Not much else here for meds.

Any help is appreciated.

It looks “brook like”. But I also think I can see tiny white dots, which would mean Marine Velvet Disease as well: https://www.reef2reef.com/threads/velvet-amyloodinium-ocellatum.217570/

I’m sure a secondary infection has also set in at this point: https://www.reef2reef.com/threads/bacterial-infections.191511/
