Hello, Sometimes fish can lose scales from minor trauma, in which case it may be fine. However, if Mr. Nugget lost his scale from an infectious disease or internal health problem, this could be the beginning of illness. I'd recommend checking his water parameters and ensuring his environment is ideal as the first step for any sick fish. I hope this is helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
