Hello all, I finally after many months of work got my planted community tank established. So I bought a school of neon tetras, I noticed one yesterday is missing his lower lip. He just has a hole where his mouth should be. I have an old 6.5 gal tank that I’ve turned into a hospital tank. I put 2 tablespoons of salt and placed him in there. So I was wondering, will he heal from this? Or should I just cut my losses and euthanize him?
