When my fish died they died one a day until all 8 fish died. They had like a white cloud over their eyes as they were dying. Then as soon as the fish died my algae problem got really bad. I discarded all my plants, changed my filter, put the light on a timer, and cleaned the glass. This weekend I would like to buy new plants and a couple of new fish and hope they live. Thanks everyone for your input I really appreciate it.
We all learn from our mistakes, and many of us have gone through such problems.
Be aware that you now have what amounts to a new tank, and it has to be cycled to establish the bacteria cycle or the new fish will be stressed and may well die. I can't see anywhere in this thread the size of your tank, but one or two fish that are hardy will cycle it with some help from you. When you buy your fish, get a bottle of Stability which is a biological bacteria supplement that will cycle the tank with one or two fish in it and prevent losing the fish. It is made by Seachem. If they don't have Stability, "Cycle" by Nutrafin will also work. Follow the instructions on the label and use it when you put the fish in. As long as you only have one or two fish, you should be OK.
