I purchase 6 black neons on Thursday and two are already dead. I have them in my cycled 10G QT. I noticed one swimming eratically on Friday, I removed him and in a matter of minutes he was dead. Immediately after that, I tested the levels and did a 40% water change. Today, I found another one dead with blood red coloring all along the top of his body. I tested the levels again and did another water change.
Levels are:
Ammonia: 0
Nitrite: 0
Nitrate:10
PH: 7.6
Any ideas?
