Came home from work today and found my 4 inch GT pretty much almost floating around... she looked fine yesterday but today she looks bad. She has lost all her color, looks like she is breathing very shallow, and also seems like white pieces of skin? or something flaking of her scales.... I put her in a bucket with luke warm water but i dont know what to do next. I messed up and I need to save my family fish... someone help...thanks. I did a big water change on Tuesday, and the tank is sitting at 74 degrees.
