kathy - that was a one and a half week situation while the 38 gallon cycled. this all happened in the 38 gallon about after it was set up. No signs of itch or anything else came to be until the filter had stopped. you have no visable idea on size, shape, and so on or how the set up looked and was created. they were perfectly fine in the ten for a week and a half, and should have been all right in the 38, but then the filter stopped while I was out of town and the outbreak started.
I will also medicate for itch. probably today, but possibly tomorrow. I also Intend to get a new filter today that give 5.27 X total gallon per hour filtration instead of the 3.8 one I currently have, and also hope it won't keep stopping like this one, and use the mature 10 media, the hopefully maturing 38 media, and then the 50's media. It's a "Stacking" modle filter, where you can add layers of filtration, medicines, ammonia suppresants and so on in it. I'd think they'd have whitespot medication where I'm going, but if not... I'll pick up the meds tomorrow.
edit:
oh, and I don't plan to do aquarium salt. That could be harmful to the eels, and definatly to the catfish.
