the fungus, since thats what everyone says it is, developed overnight. the fish died when i was at work today. i never had time to quarantine the fish. should i take out my other fish and completely take apart the tank? i dont have another tank with a heater, but i have a 5 gallon plastic bucket i could use temporarily
and no, the white stuff didnt seem to be coming from the gills. it started out right above the eye, and eventually moved up towards the top of the fish' head when it developed.
the water temp was at 80 degrees already. i have a black neon in the tank, so i can't add salt, right?
