I noticed this to my endli 2 days ago

Then this morning this also started in my delhezi

I did an 80% water change and added some salt this morning, can anyone tell me whats going on with them?
There's no aggression between my bichirs, so I decided to rule the injury from fighting.
Any help IDing will appreciated.
