Chloroquine Phosphate and lights ?

Tell her to stand on the floor barefoot and stick her hand in the tank. You'll know real quick if it's stray voltage. Typically it wouldn't kill them that fast unless it was really bad. I doubt the remaining angel would be acting normal either.

No contamination of any sort I'm assuming? I hate this for you I really do. Nothing more frustrating than losing a QTd fish, or three...

I just did a 20% water change Thursday so unless the new bag of Reg IO had a issue I can’t think of anything that would contaminate it. I guess it’s time to place a fish order and start over. It’s just really odd as I’m no QT pro but I’ve never lost fish like this.
