I just lost another fish. This is killing me :'(
I did 50% change at 9pm. Ammonia was good earlier but nitrite was 1.36.
After water change nitrite was 0.07 (test strips results attached).
Just as I was going to bed I noticed a neon tetra swimming at top and seamed like her head was floating upwards. She'd sink and swim strangely. The black Molly started nipping. This Molly nips every fish just before it dies.
I put the neon tetra in the isolation tank just to keep her from being nipped at. But she's dead now.
It all happened really quickly.
