Kreios, my PK male, died sometime this morning. A couple weeks ago he tore himself up on something in his tank (I have no idea what, he'd been in there for 2 or 3 months with no problem) and I was treating him with salt and daily water changes. But in the past couple days his wounds kept reopening (even though he was working on a bubble nest) and he suddenly died while I was away for 36 hours. It's weird because he was acting just fine, eating and blowing bubble nests the when I left Friday night, came back this morning and he's dead.
I tested the water and the only abnormal thing was the nitrite, which was either .5 ppm or 1 ppm (it was sort of in between) but I'm not sure if that's from his body sitting in the water for 12 or so hours.
But RIP Kreios. You are missed.
