I don't know wtf it is! Params are all straight, no new fish added? Actually, only thing that has changed is a pair of Godmani was removed. My Psittacus and Rotkiel are fine. I lost my smallest last night, and am now currently losing this one. The other 3 are starting to show the same signs. It started the night before last, when the one that past last night started losing it's slime coat, and sporadically shaking. This led me to think it was some kind of parasite, so I added some parasite clear. I also added some melafix. They only seem to be getting worse. I did a 50% water change this morning, and added salt. I don't know what else to do
