Everyone is like a deer in the headlights about Goni's. They are tempremental but I think the stigma comes from when people first start in the hobby, they are drawn to thier beauty and try one before they know the daily regiment of a truley keeping a consistant tank. If they try one a few years into the hobby they usually have much greater success. *knock on wood*
I more fear the carnations, often misunderstood, but they are very hit and miss also
