My otto seems to be dying. His tail won't straighten out when he swims, and he is barely reacting to anything the way he normally would. Only his gill movements tell me he is still alive. He was fine yesterday, when just did a 40 percent water change. Nothing new has been added to the tank, and my other fish doesn't bother him. Can somebody help me?
