Re: GBR with white spot?
I would not add salt, just give her clean water and lower the temps a bit. Secondary infections will thrive in the warm water. The old saying of raising temps and adding salt, cant be more wrong.
Just separate her so that she doesnt get 1) picked on more 2) stressed out from the bullying which will cause more issues. Keep the water clean, she will be fine, it is a small wound.
