I just bought a fish tank about a month ago. I changed the water today as it was dirty, using the vacuum hose to remove the dirty water. I did not empty the dirty water completely as the fish were still in the tank. I left 25% of the old water and I begin to fill the tank with fresh water using the water hose. I still had the vacuum hose inside while filling the tank with fresh water to make the water appear more cleaner. The fish appeared to be fine until the fish tank was full again and I noticed some of the fish going into some sort of shock. Trying to jump out it seems. When I turned off the water hose and remove the vacuum hose, I notice that at least 5 of my fish were floating upside down. What did I do wrong? Was it too much pressure? Was the water too warm? Help!!!
Polls: Why did my fish die? Help!!!?
