New Guinea Datnoids came in with the problem but did not show it until 1 week in my tanks. I noticed the sores and thought that 1 of the gars attacked them so I moved them to another tank and the spread started that way. It was mostly passed directly by the Datnoids o by the nets when I foolishly used them from tank to tank.
Lesson lerned for sure and now I'll be damned if it happens again, LOL.
