Originally when i first purchased my corn, he had reaaly bright colours and was really active outside his enclosure.2 weeks later,after he has benn feed twice on frozen mice that he has taken an kept down straight away he seems to have lost his brightness to a much less DULL colour.Looking at his eyes they are really milky and when i get him out of the enclosure he is really docile...Bit concerned as this is my first snake.
