That's interesting Barry. It sounds as if this thing can be cleaned off egg 
surfaces to stop the spread to another generation or tank.
I'm experimenting with 2 powerful disinfectants used in aquaculture which 
could be useful. By dipping the eggs for 50 seconds they can kill all 
viruses, Bacteria & fungal spores. Also useful as a fingertip sanitiser to 
stop eggs getting contaminated during picking.
I gave some out to a BKA lad to try out. I saw him today at one of our 
auctions & he reported that a species he was working with (whose name 
escapes me) had 24 eggs which were picked & put in a tub. All went fungus. 
The next batch of around the same amount was dipped in the disinfectant for 
a few seconds & only 2 turned bad (probably infertile).
This is not of course a definative study but it sounds worthy of further 
work.
