Emperor Blue Tetras dying

[BAT]

Hi All,

I have had a slow but consistent die off in my emperor blue tetras. I got them a year ago. They are in a tank with 15 other tetras. Around Thanksgiving an old Cory died. And I found the remnants of another fish. Then every 1-2 weeks I would find another body remnant. Any ideas why only the blue emperors would die?

What are your water parameters ammonia nitrite nitrate pH KH GH temperature. any rapid breathing hanging out near the surface lethargy spitting food out flashing sunken belly. have you introduced any new fish recently if so did you quarantine then prior to adding them to the main tank.
