Macro aids in the immune response and disease resistivity believe it or not. I believe that things appearing as ick do cause death as Wendy addresses above. I noticed a probe or maybe a heater in your picture that looks like it could be a metal outside casing? What is that?
Larry, that is a WON heater. I belive it's made out of stainless steel.
