I am stumped and so is Peter Athens. I had a group of cb satanoperca pappaterra ranging from 2" to 4" and all of a sudden they started to get what it looks like swim bladder issues. They always were swimming to fight against floating up. The day prior before they die, probably of exhaustion, their mouths will be open at all times. I have other wc geophagus species, altum angels, corydoras, and plecos, and cb gianacaras and congo tetras in with them, and only the papaterras are afflicted and dying with this issue. Sadly, I'm down to the last papaterra as the others started to die daily the span of a week.
Water is pristine as I do twice a week water changes. Temp is 78-79. I even fasted them for 3 days without any improvement. I also added 1ppt salt, which actually expedited their demise to my dismay.
I dissected one and everything that my amateur eyes could see was super healthy fish. No parasites or lesions, and the stomach was empty of contents as it died after the 3-day fasting.
Anyone has any ideas what it might be just in case it's something serious that might affect later the rest of the tank's inhabitants.
Thank you.
