I have a 55 gallon fish tank that we aquired second hand. Despite my best efforts, I've been unable to keep freshwater fish alive in it. We've cycled the tank, the water chronically tests fine, I do proper water changes, and I always add the required chemicals and additives. Still, the fish keep dying.
Is it possible that the tank itself is sick? I'm using new gravel, but the under water filter that came with the tank. The external filter is used, but the filters themselves are new. All the tank's fixtures are new. The fish were purchased at two different stores.
The only signs of illness comes on the dead fish bodies. They look bruised, as if they have internal bleeding, but this only presents AFTER the fish has died.
I wonder if the previous owner washed the tank with soap but I have no way to know for sure. Any advice on what could be going on?
