For my daughter's elementary school graduation, I bought her a GloFish 3 gallon tank kit with a Whisper filter. After establishing the tank, we added five glofish, following the directions that came with the tank. On the third day I noticed that the smallest glofish looked like the scales had been scraped off his face and he wasn't doing well. He died that night and another died the next day. The remaining fish seemed to be fine except for fighting the current in tank. I thought turning the filter off would be worse. The next morning two more fish were dead, stuck to the filter and looked mangled. Then I remembered that I could lower the flow and I did for the last fish. I kept on checking on him and at one point I saw him get sucked into the filter, so I pulled the plug and he wiggled himself out. He died a few hours later. I am extremely angry that our family has been put through this and that they are selling a product that kills the fish it is meant for!
