Powder blue dead, torches toxic?

[nbd13]

Hi,

I have a dead powder blue, I got a new torch coral a few days ago and he’s been picking at it ever since. Now he’s dead???

I also have a dead lineatus wrasse.

could I have over dosed NoPOX? Could that lower the O2 in the two k and cause death?

Hi, Ive never seen a tang die from biting any corals. The lineatus dying at the same time also points away from that diagnosis. Did the dead fish die with their mouths agape? If so, what was the timing with your NoPox addition? That can strip oxygen out of the water causing hypoxia.
