I bought two kuhlis two days ago, one died yesterday and the second seems to be dieing. Its floppy around upside down and seems to have a hard time moving, with its spine kinda bent. I can't tell if its because of handling/damage or stress, water conditions disease etc. The store people netted it just like any other fish and it was hard to get. I read taht its spine can be easily damaged, is that referring to the main spine running along its body? I also had trouble netting it, so could it be due to damage from transportation? In the bag it seemed fine swimming around, then I netted it in the tank, where it quickly dissapeared in the moss clump I have. Then, a day later one of them was found dead on its side. Today, the lone survivor is flopping around seemingly in distress and unable to get up or swim right.
