lol yea theres a small chance it could be something wrong, so better safe than sorry check water quality and do a water change...
but i think its important to note that most blood parrots have a mutuated cornea/pupil. One of the unintended consequences of the hybridization is a misshapen or larger pupil pushing into cornea... no telling how this affects their vision but it is a common occurance, esp with later generation bp and seems to be more prevalent in the RED blood parrots. so it could just be a mutation but its always a good thing to check your water and clean the tank.
interestingly enough though, I have noticed that they can change the shape of their pupil when looking at different objects... like dilation but expressed differently... I used to have a parrot with a triangular pupil that would change to round when she was looking at something up close.
wierd
