Hi we had gotten a African Featherfin Catfish at our LFS. Hes doing really well but I have noticed his body is changing. He is dark with small spots you can't really see and on all his fins they have vertical stripes. I'm worried because I've noticed these random beige markings on his body. He usually stays in his cave so I can't get a close look at him. But hes never had them before. Just wondering if anyone has experienced this before. Other than that he eats and is healthy.
