My little axie was fine yesterday and now I go and look and the tank and its tail is broken and has fungus all over its body. What should I do? I think it will die because it is trying to move but just flips onto its back. It has this white stuff coming out of its bum what is that? Should I bother putting it in salt because will that just stress it out and make it die quicker? It was not the water that caused the fungus because the water is all clean and the levels are all good. I think it was the broken tail that caused the fungus. I dont know how it broke its tail it might have been my other axie biting it.
