Thanks for the info, I never knew about internal columnaris. The deaths
spread like wildfire, a matter of hours. They started getting white areas
that just kept growing until it covered all transparent areas on the fish.
Also lost one z.danio. Can anyone recommend a gram-negative antibiotic?
Most of the stuff I've seen is gram-positive.
=========================
Furicin and Furinace should get both gram negative and gram positive
bacteria. I think I got the spelling correct. Foster & Smith and I believe
That Fish Place both carry it.
