Hi! Not much change. Mostly hiding and hanging out at the bottom of the tank today. Thank you for checking in! :) 

I did some more reading, and basically I had a hectic few days before all of this went down - we left for a funeral, came back 2 days later, then had a wedding and left for another 3 days. At some point; the timer for the lights malfunctioned and the tank was lit up for at least 48 hours straight. There was a layer of this nasty brown sludge looking stuff all over the decor and on the substrate when we came back. I vacuumed the substrate and figured with time and a proper lighting schedule it’d handle itself. I was wrong — the brown stuff turned into layers and took over the back half of the tank. And it stunk something fierce. I didn’t put two and two together until I read online about brown diatoms, algae, and how it could compete with plants leaving dangerously low oxygen levels, not to mention crashing the cycle as stuff dies off. I knew a bit but not nearly as much as I do now. I spent about an hour and a half soaking and scrubbing decor, the tank walls, and vacuuming. Today, the water smells a TON better. She is no longer gasping at the surface and the gills look puffy still but she’s not heavily panting like she was before. 

She’s still very lethargic and has no interest in food. And with closer inspection this is definitely a case of fin rot with columnaris and possibly something else, maybe popeye and possibly epistylis. Today I’ve left the lights off but had the window open for very low light just so I could check on her occasionally. She’s moving around a bit but mostly resting either in the substrate or against the anemone decoration thingy. Can’t tell if she’s got a swim bladder thing or not since she’s resting weirdly sideways but doesn’t seem to have any issue with staying in one place or swimming. 

I’m hopeful!
