Koran Angel losing color

[Josecuervo1]

Hello !! I have had my Koran Angel for 3 weeks now. he showed a very small amount of ich not too long ago but seem to have gotten better. He's swimming great, eating very good (Ocean Nutrition Angel Formula + Dr. G's medicated foods + mysis shrimp mix ) plus he and my sailfin both love the algae I put for them on a clip. But for a few days I have noticed his body losing color and have no idea how to treat it......PLEASE HELP !!!
Thanks in advance

How large is he? Is he starting to change into his adult colors? You can google Koran and you'll be able to see images of the juveniles in transition changing into adult colors...mine was about 4 inches when he started. Good luck!
