Okay, let's start at the beginning. Every species of tetra ever added to my tank has died. Every one.com no reason why. It started with Rummies then Kerris and now penguins. They just randomly die. Most recent is the penguin tetra die off. I had twenty four go into my 60 g tank. They were fine for a week. Then there y started.d slowly dying day by day. Now I have none. Then, a few otos started dying. And today, my beloved Apisto died. I don't know what else to do. These fish were all fine before they died!! All eating, swimming, healthy. Parameters are perfect, and always have been. Water changes occur on Saturday, 50%. I do dry ferts as well. There are no aggression issues in the tank and they werent killed by others. I can't figure this out and I don't want anymore fish until it is. Does anyone have similar experiences or ideas why this is happening to me?
Thanks
