This has been a real bad *$#%ing day - warning pics are not good natured

Here I thought the worse was over, but then I clicked on the post and you were amassing more losses. The only thing I can think of is that the h2s posioning took out your benificial bacteria, how are the water parameters looking? You were still running large amounts of carbon so it should not have been anything else toxic. Maybe a bacteria that was able to spread with the fish stressed from being moved, and with the additon of h2s it was able to attack their weaken immune systems. I am sorry to hear that it has not gotten better, and it's always worse not being able to figure out the cause, hopefully you'll be able to stick in there and continue being in this hobby.
