I bought four fish and a tank a month ago. All was fine until yesterday, three of my fish have suddenly died - they were floating upside down. The recent one just started floating on its side and the skin turned white and was all flaky. I'm not sure whether it has something to do with my tank? Does putting water clarifier and water conditioner together affect the fish? Also, the tank water has gone green even though I changed the water right before.
