I did a bad thing. I doubled my rummy nose tetras too soon. I went from 12 to 23 the next day. I caught the spike this morning and did a 50% water change. Note, I tested the water yesterday as well because I lost my senior kuhli. Nothing was out of the ordinary yesterday.
As a result of this spike, I noted red streaking on my angels. I feel horrible. Will they recover from the streaking? Should I return half of my rummy school?
I just feel absolutely horrible and I should of known better.
