No, it was ich. We took a shed to work and looked at it under a microscope. I usually just suck them out now, but the next one I'll look at again to see what's there.
About the food in the room. We cinformed the ich was on the fish, hence in the tank, by the microscope. They aren't going to die off with the fish still being in there (food in the room = fish in the tank). Does that make sense. I know some say they only interbred a certain number of times and then they sort of fizzle out..... as in last only a few generations. I'm not sure I believe that.
Scorps are famous for having ich but are also excellent at avoiding infestations because they shed. They do this shed for the very purpose of getting rid of parasites and algae growth due to their sedentary lifestyles.
