Angel fish question

[Av3206]

Hello new to keeping angel fish I ordered the koi variety and I noticed in there head area some have very red spots almost look like a collection of blood. Is this normal or not?

Ok thanks was like ummm why are there gills filled with blood and of course when you try to google that only bad things come up!

The red cheeks are what makes them a KOI and not just a Goldmarble. They have two stripeless genes which makes their gill plates transparent until they grow older. It is called "Blushing". A Goldmarble angel will be the same color only without the transparent gill plates.

They look like they have blushing angels somewhere in there lineage.
