Albinos practically all have red / pink eyes.
one of my marbles has a red line in it's eye.
Not very rare in the UK.
True peruvium altums are about as rare as angels get over here and would command a price of around £150 (mine is worth about £200 and is only 3"!)
I heard once that angels that have red eyes are more 'wild' than angels without red eyes. I don't remember where I heard this, has anyone else heard something like this?
