Is My Head And Tail Tetra Ill

[Bectopher]

My husband and I are new to the hobby of tropical fish. we have a group of 5 head and tail tetras and one of them I am concerned with as its black dots on the front and tail area isn't as vibrant in colour as the other 4. Can someone tell me if it is anything we should be concerned with?

Nothing to be too concerned with, some fish just don't have colouring that is as vibrant.
If you think it could be something just keep an eye on it or post pictures on here.
