Sunset Platys Red Gills

[simon1985]

I have 8 Sunset Platys and all of them have redish gills. Is this normal for sunset platys? is it part of their colouration?

I only ask because none of the other fish have red gills.

BTW, opinions on my tanks stock, 20 Gallon hex tank, 1x Bristlenose plec (female around 6inch), 3x Glass catfish, 1x Phantom tetra, 1x guppy, 8x Sunset Platy (2 are 3months old), 4x Amano Shrimps. and id like to get 1 or 2 assassin snails.

incase anyone does care to look, here are some pictures.

Basically it's coz the gill membrane is opaque. All Gills are red, as blood is pumped through them to absorb oxygen from the water.

So it's not a problem

They all seem happy enough, swimming about alot and the males chase the females. They dont beath heavy or anything.
