I have skimmer running, and 2 hang on filters with surface agitation for oxygen in water, on top of the powreheads. I did not wait, as soon as my foxface died, I began the large water changes, during which the scopas died, and now a few hours later, I have done a large water change, and put in activated carbon to clean up anything. I also lost a yellow headed sleeper goby, and a six line wrasse, now all I have is the pair of clowns, who act unchanged, just fine. Also, all inverts and shrimp are moving around tank like nothing happened. I am confused, I do not have any residue on my arms or hands when I do tank maintenance, I now use nonpowdered latex gloves also, there have been no chemicals like lysol or windex near the tank, nor any bug spray or such, so I am just as confused.
