I came home last night and found my yellow tang lying at the bottom breathing heavily. I checked the water parameters. They are as follows:
PH 8.2
ammonia 0
Nitrites 0
Nitrates 40
Spec Grav. 1.022
He was dead when I woke up. I don't know what happened, there were no visible signs of disease. I did add some rock to the tank yesterday, but all the other fish are fine. Wouldn't is all of them if I accidentally introduced a contaminant? Any ideas what could of happened???????
