I Think My Black Ghost Knife Is Sick!

[sic0198]

I've had it for a few months, minutes ago I looked at my aquariam and I saw my BGK out swimming around. It is close to 5 or so inches and I noticed a brown spot on both sides of it. I thought fish disease (white spot and Ick etc) was normally white. Anyway what is these brown spots? How can I medicate this? His tail looks longer too and it may be changing color too, or I may be seeing things. Help!!!

I didn't really know at the time if it was sick or just a natural occurance.
