I mean is that when you look at the gills of a goldfish as in if there pink, red or what every color. Do you look under the flaps and look at the gills? if so here is a pic of Golden my 3 year old fantail goldfish. Im the one that posted before on something was wrong with her. I have her in hre own tank and trying to see what's wrong with her.

Yep... You're looking in exactly the right spot. Your fishes gills look fine to me.

Good, than her gills are back to normal....... She is so used to being checked so she was ok with me looking at her gills...

That is a very neat shot of your fish's gill!! Perfect! ....

yah no kidding some one may want to book mark it for futcher refrances to gills, i know its come up a few times.
