The blue is not in the iris itself, but in the surrounding of the eye and then it shows as a sky blue colour. To be honest I don’t see this from these shots as 100% a blue eyed lemon, but it’s over 50% is a female long fin BEBN but could just be a lemon BN. As this is an adult a shot from above would/ should show the blue much clearer.
The problem is that many blue eyed lemons are kept with brown bristlenose and both inter breed.
More often than not the one parents genes determine the colour of the young fish, although the colour of the eyes varies, so it is possible to end up with lemon coloured bn with normal eye colours. These then get sold back to shops as blue eyed lemons.
Often with these cross bred bn you also see brown patches appearing on some of the young fish and these stay into adulthood. Of course this kind of crossing is how we get calico bn and to some extent how we get the reds and super reds, which often exhibit some level of brown mottling or brown speckling coming through.
