Poor Sir Reginald has some tail issues. He looked great this morning when I left, and when I got home his tail looks ragged. It doesn't look dark around the edges and otherwise he looks and is acting fine. He recently got moved to the display tank, which is heated. He is extremely lively in his tank, as opposed to being more lethargic in the unheated hospital tank while I checked him out for any health issues. He seemed fine then.
All I can find about tail biting is that it seems to be stress related. Other than keeping him in clean water, which I do anyway, what can I do to help him heal?
