[Otocinclus skin disease???]

Ok I’ll definitely give that a try. 🤞 thanks for your input! 

[Otocinclus skin disease???]

Water parameters were checked with the API master kit and they are all good. I currently have 4 of them together in a planted 15 gallon tank. Another picture with his/her little shrimp buddy checking up on ‘em. I’ve had these otocats for 5 months now but this one is slowly turning white. It does swim around with the others and eats just fine. Would this just happen to be a rare case of albino-ism?

Hey guys/gals! I have an otocat here with a weird skin pigmentation and was wondering if anyone can offer any advice on what it is.
