Diamond Crystal Kosher salt does not contain an anti-caking agent. Available at supermarkets and on line.

What does it mean if a fish is swimming INTO the glass? Not against the glass like glass surfing, but actually like slowly/gently swimming into the glass, not ramming himself, just pinning his head to the glass as he swims forward.
And it seems to only be ONE section of the glass. Not just random
And sometimes he moves up or down, like he is glass surfing, but mainly it's just staying in one area

That's a good question. Corys will slowly work the glass to eat biofilm. Could it be that?

Maybe, but he's the only one doing it and he's the one with the physical head damage from earlier, which is why it makes me a bit more worried.
Hopefully it's just that though.
I only noticed this behavior yesterday

How does the fish look now?
Any better or is it worse?
