Hello! Today while I was taking picture of my fish, I noticed on his tail he had this dull yellowish spot on it. I can't tell you how long its been there since I just noticed it.
Other than the spot, he's acting like his normal grumpy self. Is this just part of his coloring or something else?
Sorry if the picture is too big.
