Need a picture there are some white cories running around does it have pink eyes or black eyes. Some of my albinos have 1 black and 1 red not many but every 20 drops or so some show up.
there is a possibility it is a cory that normally would be dark, coloured, or patterned but may have what is called leucism. this is where there is no pigmentation except for the eyes. I have a peacock cichlid i believe has leucism.
