Royal Pleco orange fins and tail

[peewee]

I just would like to ask if this is normal for a royal pleco to develop orang coloration on the tips of its tail and fins? Mine behaves as usual and eats like a pig but i noticed that it developed these orange coloration on its tail and fins as it starts to grow, it's currently around 7 to 8 inches, it's a typical looking royal when i bought it but it looks lile this now

Seen some panaque plecos with some yellow fins and tails. It’s not uncommon I believe.
