Hello,

I am new to this hobby, and think a couple of my fish are sick. I have a medium yellow tang with small black spots and overall lackluster color. I assume the black spots are black ich? I also have a lemonpeel angelfish with one eye that is cloudy and puffed out.

All of my water tests seem to be fine, and the salinity is within normal ranges. How can I tell if there is something else going on with the water? How do I know if the live rock is "live" or otherwise healthy?

A little background on what I have:

120 gallon tank
100 pounds of live rock
Pro 150 Wet/Dry with Prefilter


Thanks,
Zach
