Well she's doing better today. Breathing is still fast but slower. She's off the bottom a bit more but not swimming around the whole tank, just hanging out in that corner. I tried NLS pellets and she attempted to eat them but spit them out (previously was eating them). I then fed a frozen mixed food (mysis, krill, brine, bloodworm) and she ate a good amount. Progress seems to be happening but I'm still stumped.
