I woke yesterday to find my clown sick or injured, I am not sure which. She has a small piece missing out of her tail. She was fine the night before so I am thinking it happened during the night. Well now she is just hanging in one corner and barley moving. Her color is fine and there are no other marks on her body. When I feed she can't swim to the food. I try to put it right over her but that doesn't help either. Her breathing is not fast. She was tank raised and I have had her since January. Is the nip in her tail just throwing off her balance or could it be something worse and do I need to put her in the QT and start medication. If so, for what???
