Hello; The fact that you suspect the fish may have been exposed to a serious disease should be enough to determine that they should not be placed with other fish and should not be taken to anyone else's tank. If you do not want to put them down, then keep them in a tank together until they live out their time.
Hello everyone. I am really disappointed to say that the last surviving danio died today, which is pretty much the last straw for me. Since I read online that loaches are a rare exception and don't get affected by the disease, I will be eradicating them to a temporary 2.5 gal while I empty and tear down my 40, and replace the entire tank to get rid of that darn thing. I'll be euthanizing the remaining neon and two barbs before it's too late. Does anyone know what I Gould use to freeze them? My dad has been euthanizing sick fish like this for a long time but he says he doesn't remember what he put them in to freeze. It's been a long battle and I finally found a solution without an easy way out, but then again nothing worth it ever is; am I right, boys?
