I have been keeping fish for the last two years and have never seen anything like this before.When i checked the gills of the dead fish they looked good,red not damaged. The fish didnt have any thing wrong with them. Could it be some substance that has contaminated the tank. I leave my water new water standing over night to make it warm maybe something went in there.
What do i do if the water is contaminated ?
